Bruton\u0027s tyrosine kinase (BTK) is central to B-cell receptor signaling and is therefore an important therapeutic target in CLL. Despite the revolutionary impact of BTK inhibitors on CLL therapy, acquired resistance and treatment related toxicities are still major problems. PROTACs represent an alternative approach to therapy in that rather than simply inhibiting the activity of a disease relevant protein they work by recruiting an E3 ubiquitin ligase to promote the degradation of that protein. The development of PROTACs as therapeutics has been hampered by a lack of understanding of the molecular determinants that govern degradation, poor drug like properties and a lack of cellular selectivity. To overcome these limitations we have developed amino acid-linked PROTACs (AAL-TACs), a modular platform that incorporates a stereochemically defined amino acid linker between the target binding and E3 ligase binding ligands. This provides a platform for systematic variation of degrader structure and also provides a functionalizable chemical handle for targeted delivery. Our initial studies have shown that amino acid identity, stereochemistry and linker architecture all have a significant impact on BTK degradation with lead AAL-TACs achieving nanomolar potency. Both experimental and computational data suggest that the differences in degradation activity between stereoisomers are due to differences in ternary complex formation rather than simply differences in binary ligand affinity. The proposal aims to establish the molecular design principles that govern AAL-TAC mediated BTK degradation and to engineer delivery strategies that improve cellular selectivity. First, we will look at how the amino acid linker architecture affects target engagement, ternary complex formation and downstream CLL signaling. Second, we will develop AAL-TAC antibody conjugates that will utilize CD19 mediated recognition and internalization to deliver BTK degradation specifically to malignant B cells. Third, we will engineer AAL-TAC lipid nanodisc conjugates and assess how nanodisc architecture and SR-B1 interactions impact intracellular delivery and degradation activity. We will assess both delivery platforms for selective BTK degradation in relevant CLL models. By combining molecular engineering, chemical biology and targeted drug delivery we aim to establish a framework connecting degrader architecture to intracellular activity and cellular selectivity. The work has the potential to lead to more effective therapies for CLL and to provide broadly applicable design principles for targeted protein degradation.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EDesign and development of amino acid-linked PROTACs for targeted protein degradation\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Design and development of amino acid-linked PROTACs for targeted protein degradation"}],"uid":"27707","created_gmt":"2026-10-28 19:42:51","changed_gmt":"2026-10-28 19:43:17","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-09T14:00:00-05:00","event_time_end":"2026-11-09T16:00:31-05:00","event_time_end_last":"2026-11-09T16:00:31-05:00","gmt_time_start":"2026-11-09 19:00:00","gmt_time_end":"2026-11-09 21:00:31","gmt_time_end_last":"2026-11-09 21:00:31","rrule":null,"timezone":"America\/New_York"},"location":"N357 HSRB II ","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693598":{"#nid":"693598","#data":{"type":"event","title":"PhD Defense by Jose Maria Ferdinand Victoria Calaunan","body":[{"value":"\u003Cp\u003ESchool of Civil and Environmental Engineering\u003Cbr\u003EPh.D. Thesis Defense Announcement\u003Cbr\u003EClay-Rich Geomaterials: Implications for Infrastructure Stability, Critical Mineral Recovery, and Nuclear Waste Isolation\u003Cbr\u003EBy: Jose Maria Ferdinand Victoria Calaunan\u003Cbr\u003ESEB 122\u003Cbr\u003Ehttps:\/\/gatech.zoom.us\/j\/95498188644\u003Cbr\u003E2026-11-11 1:00 PM EST\u003Cbr\u003EDr. Susan Burns, Dr. Sheng Dai, Dr. Angel Palomino, Dr. Anne-Catherine Dieudonn\u00e9\u003Cbr\u003EClay minerals are phyllosilicates formed through rock weathering and precipitation. Parent-rock chemistry and drainage conditions influence their layered structures, giving rise to different minerals, including 1:1 kaolinite and 2:1 montmorillonite, illite, and chlorite. Their mineral structure and interactions with water and ions result in multiphysics behavior that spans scales from mineral surfaces to sedimentary layers. Clay platelets develop preferential alignment and form tactoids during burial, yet the tactoid scale remains poorly explored. How do tactoid organization and hydration influence mechanical behavior? Thin bentonite films serve as analogues of organized tactoid assemblies. Microscopy, suction measurements, nuclear magnetic resonance, and mechanical testing of thin films reveal preferentially oriented fabric and hydration-dependent stiffness and tensile capacity. These measurements provide tactoid-scale properties for numerical upscaling simulations. The connection between particle arrangement and mechanics extends to large-strain friction, where platelets and tactoids align within shear zones. A curated database compiled from published studies shows that the residual friction angle generally decreases as liquid limit increases, in agreement with previous studies. However, mineralogy, fines fraction, displacement rate, and extent of shear displacement also affect the large-strain shear response. The broader relationship is conceptualized as an n-dimensional response manifold. Charged clay surfaces retain counterions such as those released from neighboring rock weathering. How are rare earth elements retained in clays? Can they be desorbed and recovered? Experiments reproduce the adsorption history to form dysprosium-bearing kaolin, as confirmed by multiphysics analytical measurements. Subsequently, clay pastes subjected to a voltage gradient show the potential of electrokinetics in mobilizing and replacing previously adsorbed rare earth elements. The external fluid chemistry affects mobilization and may lead to counter-gradient migration. While calcination causes localized booklet opening and destructuring of the octahedral layers, it locks in the high-valence ions and hinders the recovery of rare earth elements. Overall, clay pretreatment and electrolyte chemistry jointly control rare earth element accessibility, mobilization, and collection. Clay surface chemistry, particle-fluid coupling, and particle-particle interaction can be altered under extreme conditions, affecting the properties and performance of the clay mass. In particular, can intense radiation compromise bentonite buffers used in nuclear waste disposal? A comprehensive study examined bentonite specimens exposed to beta and gamma radiation doses ranging from 100 to 2000 kGy. Results show that bentonite largely preserves its surface chemistry, hydration, particle associations, and swelling potential. These findings indicate that bentonite exhibits high radiation resistance under the investigated storage conditions. Together, these studies connect the multiscale organization and multiphysics behavior of clays and provide renewed insights relevant to mechanical stability in engineering design, critical mineral recovery, and nuclear waste isolation.\u003Cbr\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EClay-Rich Geomaterials: Implications for Infrastructure Stability, Critical Mineral Recovery, and Nuclear Waste Isolation\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Clay-Rich Geomaterials: Implications for Infrastructure Stability, Critical Mineral Recovery, and Nuclear Waste Isolation"}],"uid":"27707","created_gmt":"2026-10-28 19:18:49","changed_gmt":"2026-10-28 19:19:21","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-11T13:00:00-05:00","event_time_end":"2026-11-11T15:00:13-05:00","event_time_end_last":"2026-11-11T15:00:13-05:00","gmt_time_start":"2026-11-11 18:00:00","gmt_time_end":"2026-11-11 20:00:13","gmt_time_end_last":"2026-11-11 20:00:13","rrule":null,"timezone":"America\/New_York"},"location":"SEB 122","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693592":{"#nid":"693592","#data":{"type":"event","title":"PhD Defense by Lauren Daley","body":[{"value":"\u003Cp\u003ELauren Daley\u003Cbr\u003EBME PhD Defense Presentation\u003Cbr\u003E\u003Cbr\u003EDate: 2026-11-11\u003Cbr\u003ETime: 3:00pm\u003Cbr\u003ELocation \/ Meeting Link: HSRB Auditorium or \u003Ca href=\u0022https:\/\/emory.zoom.us\/j\/99567578053\u0022\u003Ehttps:\/\/emory.zoom.us\/j\/99567578053\u003C\/a\u003E\u003Cbr\u003E\u003Cbr\u003ECommittee Members:\u003Cbr\u003EShella Keilholz, PhD (advisor); Lynn Marie Trotti, MD; John Oshinski, PhD; Candace Fleischer, PhD; Vince Calhoun, PhD\u003Cbr\u003E\u003Cbr\u003E\u003Cbr\u003ETitle: Cross-species characterization of spatiotemporal patterns from rs-fMRI data across states of wakefulness\u003Cbr\u003E\u003Cbr\u003EAbstract:\u003Cbr\u003EFunctional MRI (fMRI) is vitally important to the field of neuroscience; several key findings cite fMRI studies as primary evidence to support those claims. We understand fMRI to represent a proxy of neural activity, not a true capture of real-time neuronal activation, but a time-lagged hemodynamic response. fMRI signal, both resting-state and task-based\/stimulation-evoked, has been acquired in many species, finding several preserved resting-state networks and task responses. However, there are still key gaps in cross-species fMRI experiments, including fully elucidating how arousal or wakefulness state impacts the resultant signal, establishing robust and reproducible awake mouse protocols, and the ongoing debate of time-averaged versus time-varying methods. This thesis employs several fMRI datasets spanning across species (human, mouse), field strength (3T, 9.4T), acquisition sequence (Echo Planar Imaging, EPI; Zero Echo Time, ZTE), analysis method (functional connectivity, FC; quasi-periodic pattern, QPP; complex principle component analysis, CPCA), and, most importantly, across state of wakefulness (awake, asleep, anesthetized). Using clinical data from the Emory Sleep Center that spans across diagnostic criteria for hypersomnolence disorders, I first establish the human arm of this axis. I then developed a robust protocol for acquiring awake mouse fMRI data, and from this data, established the mouse arm of this axis. This awake mouse fMRI provides the cross-species homologue for awake, resting-state human fMRI, and was tested via a feasibility study of the MitoPark mouse model. Upon completion of these individual projects, I then identified preserved resting-state and large-scale brain networks, notably the Default Mode Network (DMN), and Somatomotor Network (SMN). These network interactions acted as the basis for the proposed cross-species axis of arousal, finding tightly-coupled relationships between DMN and SMN strength and activation with state of wakefulness. This axis will hopefully act as a guide for researchers in designing future fMRI experiments, particularly pre-clinical experiments aimed at translational research.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003ECross-species characterization of spatiotemporal patterns from rs-fMRI data across states of wakefulness\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Cross-species characterization of spatiotemporal patterns from rs-fMRI data across states of wakefulness"}],"uid":"27707","created_gmt":"2026-10-28 17:38:02","changed_gmt":"2026-10-28 17:38:37","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-11T15:00:00-05:00","event_time_end":"2026-11-11T17:00:00-05:00","event_time_end_last":"2026-11-11T17:00:00-05:00","gmt_time_start":"2026-11-11 20:00:00","gmt_time_end":"2026-11-11 22:00:00","gmt_time_end_last":"2026-11-11 22:00:00","rrule":null,"timezone":"America\/New_York"},"location":"HSRB Auditorium ","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693590":{"#nid":"693590","#data":{"type":"event","title":"PhD Defense by Hanna J.

They are less explicit about how adoption intentions form when a technology is not yet available, its operation and consequences are difficult to understand, and reliable evidence concerning performance, failure, or misuse is limited. This dissertation developed and tested the Model of Acceptance of Futuristic Technologies (MAFT) to explain early adoption intentions under these conditions of experiential and informational uncertainty. Across three studies, flying cars were used as an exemplar futuristic technology. The research program combined assessments of prior beliefs and discrete emotional responses, structural equation modeling, and pre-post simulated exposure delivered through desktop-based 360 video and immersive virtual reality. The findings indicate that prior beliefs and affective responses provided an initial interpretive framework through which perceived value, trust, and risk were evaluated. These judgments formed an affectively organized pathway associated with adoption intention, with perceived risk playing a less dominant role than originally anticipated. Although psychological distance contributed to the broader framework, the findings placed greater explanatory emphasis on affective and evaluative processes. MAFT extends technology acceptance research by explaining how people evaluate emerging technologies before meaningful experience and reliable performance evidence are available. The findings suggest that responsible communication, design, and governance should support appropriately calibrated beliefs, affective expectations, and trust by presenting realistic benefits, limitations, uncertainties, safeguards, and error modes. Such calibration may reduce both overtrust and unwarranted rejection of technological novelty.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cstrong\u003E\u0026nbsp;Development and Validation of the Model of Acceptance of Futuristic Technologies (MAFT)\u003C\/strong\u003E\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":" Development and Validation of the Model of Acceptance of Futuristic Technologies (MAFT)"}],"uid":"27707","created_gmt":"2026-10-28 17:13:41","changed_gmt":"2026-10-28 17:14:08","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-13T09:00:00-05:00","event_time_end":"2026-11-13T11:00:00-05:00","event_time_end_last":"2026-11-13T11:00:00-05:00","gmt_time_start":"2026-11-13 14:00:00","gmt_time_end":"2026-11-13 16:00:00","gmt_time_end_last":"2026-11-13 16:00:00","rrule":null,"timezone":"America\/New_York"},"location":"JS Coon 148 or online","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693577":{"#nid":"693577","#data":{"type":"event","title":"PhD Defense by Megan Arogeti ","body":[{"value":"\u003Cp\u003EIn partial fulfillment of the requirements for the degree of\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EDoctor of Philosophy in\u0026nbsp;Physics\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ESchool of Physics\u0026nbsp;Thesis\u0026nbsp;Dissertation\u0026nbsp;Defense\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EMegan Arogeti\u0026nbsp;\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EDr.\u0026nbsp;Laura Cadonati, School of Physics, Georgia Institute of Technology (Advisor)\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EGravitational Wave Signal Reconstruction and Binary Neutron Star Postmerger Detection Using Stacking Methods\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EDate: Thursday, November 5, 2026\u003C\/p\u003E\u003Cp\u003ETime: \u0026nbsp;12:00 p.m.\u003C\/p\u003E\u003Cp\u003ELocation:\u0026nbsp;CRA\u0026nbsp;Seminar Room (College of Computing) CCB 103\u003C\/p\u003E\u003Cp\u003EVirtual:\u0026nbsp; \u003Ca href=\u0022https:\/\/teams.microsoft.com\/meet\/240561325650301?p=nvL8ezZRRym7CDoxSV\u0022\u003Ehttps:\/\/teams.microsoft.com\/meet\/240561325650301?p=nvL8ezZRRym7CDoxSV\u003C\/a\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EThesis Committee:\u003C\/strong\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EDr.\u0026nbsp;David Ballantyne, School of Physics, Georgia Institute of Technology\u003C\/p\u003E\u003Cp\u003EDr.\u0026nbsp;Gongjie Li, School of Physics, Georgia Institute of Technology\u003C\/p\u003E\u003Cp\u003EDr.\u0026nbsp;John Wise, School of Physics, Georgia Institute of Technology\u003C\/p\u003E\u003Cp\u003EDr.\u0026nbsp;Edoardo Milotti, Physics Department, University of Trieste\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EAbstract:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003ESeptember 14, 2015 marks the date of the first direct observation of a gravitational wave (GW). In the ten years that followed, the LIGO-Virgo-KAGRA (LVK) collaboration has observed hundreds of signals from merging compact binaries. Beyond measuring the extremely small distortion of spacetime caused by a passing gravitational wave, detecting and interpreting these signals requires advanced techniques. In this talk, I discuss two aspects of GW data analysis: validating the reliability of modeled waveforms and pushing our detection sensitivity beyond the limits permitted by individual events. I begin with a review of gravitational-wave astronomy and LVK observations. I then describe a method where we compare a source-agnostic reconstruction of a gravitational wave signal to a best-fitting waveform from a template-based analysis used to infer the source\u0027s properties. This test allows us to validate the efficacy of our waveform models and establish whether they are able to accurately describe the data. I report the results of my work applying this analysis to events from the fourth LVK observing run. In the second part of this talk, I first review the gravitational wave signals produced by a deformed binary neutron star (BNS) postmerger remnant. BNS postmerger signals carry information about the dense matter within neutron star cores, and could, therefore, be a direct probe into the properties of matter under some of the most extreme conditions. However, these signals are expected to be emitted at frequencies between 1-4 kHz, where detector sensitivity is reduced, making them extremely difficult to observe. For the next LVK observing run, the probability of a confident individual postmerger detection is well below one per year. With detector improvements, and especially third-generation detectors, we expect an increase in the number of BNS inspiral detections, some of which may contain postmerger emission that is too weak to be detected on its own. I therefore introduce a method for combining signals from multiple events in their time-frequency space to enhance postmerger detection probabilities.

Endoscopic imaging plays a crucial role in the diagnosis and clinical management of many GI diseases, including GI cancers, gastroesophageal reflux disease, and inflammatory bowel disease (IBD). However, its invasive nature deters individuals from recommended testing and hinders its routine use as a monitoring tool. Non-invasive tests for detection of blood and fecal biomarkers are used in the clinic, but either have poor sensitivity for early detection or poor disease specificity. For these reasons, there remains a critical unmet need for non-invasive tests for GI disease.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EBreath tests are a highly attractive alternative to endoscopy because breath can be sampled non-invasively and analyzed for disease-indicating volatile organic compounds (VOCs) (\u003Cem\u003Ei.e.\u003C\/em\u003E, breath biomarkers). However, few breath biomarkers have been successfully identified due to technical and statical limitations of conventional -omic approaches. In this work, we have developed an approach to induce exhalation of breath biomarkers to diagnose and monitor GI diseases. Our strategy uses new ingestible molecular probes, which release volatile reporters upon activation by disease activity in the GI tract. Once released, reporters are rapidly cleared from the body in breath and measured via mass spectrometry.\u0026nbsp;Thus, probe ingestion induces exhalation of pre-specified volatile reporters of known mass to indicate disease activity (\u003Cem\u003Ei.e.\u003C\/em\u003E, synthetic breath biomarkers), obviating the need for biomarker discovery.\u003C\/p\u003E\u003Cp\u003EOur approach leverages dysregulated glycosidase activities, which play a central role in the pathogenesis of diverse GI diseases. The GI tract houses hundreds of distinct glycosidases from the host and microbiome that regulate gut barrier function, mucosal immunity, host-microbe interactions, and the metabolism of drugs and dietary sugars. In \u003Cstrong\u003EAim 1\u003C\/strong\u003E, I establish design principles for the ingestible probes and develop a probe to monitor the activity of a microbial glycosidase that causes drug-induced GI toxicity. In \u003Cstrong\u003EAim 2\u003C\/strong\u003E, I use the established platform to develop a probe for a human intestinal glycosidase which, when deficient, leads to a sugar malabsorption disorder. I further demonstrate how induced breath signals can be detected via novel carbon nanotube detection arrays, a low-cost alternative to mass spectrometry. Lastly, in \u003Cstrong\u003EAim 3\u003C\/strong\u003E, I demonstrate the multiplexing capabilities of our platform and assemble a volatile-barcoded probe array to induce breath biomarker signatures of mucosal injury and healing in the context of IBD.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cstrong\u003EEngineering ingestible probes for breath-based detection of gastrointestinal diseases\u003C\/strong\u003E\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Engineering ingestible probes for breath-based detection of gastrointestinal diseases"}],"uid":"27707","created_gmt":"2026-10-28 15:52:08","changed_gmt":"2026-10-28 15:52:38","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-11T14:00:00-05:00","event_time_end":"2026-11-11T16:00:00-05:00","event_time_end_last":"2026-11-11T16:00:00-05:00","gmt_time_start":"2026-11-11 19:00:00","gmt_time_end":"2026-11-11 21:00:00","gmt_time_end_last":"2026-11-11 21:00:00","rrule":null,"timezone":"America\/New_York"},"location":"EBB CHOA Seminar Room","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693574":{"#nid":"693574","#data":{"type":"event","title":"PhD Defense by John Stavroulakis","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003EDate: Thursday, November 19th\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ETime: \u0026nbsp;11:00 am\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ERoom: Skiles 168\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ETitle:\u003C\/strong\u003E On the bow lemma and higher dimensional analogs.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECommittee\u003C\/strong\u003E: Igor Belegradek, Elena Braverman (University of Calgary), Mohammad Ghomi (advisor), Galyna Livshyts, Andrzej Swiech, Erik Verriest (ECE).\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EAbstract:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EWe discuss the bow lemma or Schur comparison theorem, and in particular its higher dimensional analogs.

The results of this study were thematically analyzed and produced roughly 40 themes, which were then used to create the General Technology Mastery Scale (GTMS) through a series of factor analysis techniques. The GTMS then underwent a series of validation testing through comparisons with hypothesized covariates based on the literature (such as problem-solving, technology self-efficacy, general self-efficacy, technology acceptance, system usability, locus of control, motivation, and creativity). Finally, the GTMS was deployed in a classroom setting to assess within-subjects growth in mastery, motivation, and problem-solving ability.\u0026nbsp; This dissertation contributes a consolidation of the work done in technology mastery and fluency, in addition to providing validated psychometric measuring techniques to assess technology mastery.

Learning these interdependencies is particularly challenging in decentralized environments where raw data cannot be shared, and individual subsystems operate proprietary models that cannot be modified. This dissertation develops decentralized learning frameworks for characterizing cross-client temporal interdependencies in both linear and nonlinear dynamical systems while preserving the autonomy of individual client models. For linear systems, we establish a federated Granger causality framework that enables the discovery of unknown cross-client interdependencies. We further use this federated Granger causality\u0026nbsp;framework to investigate the propagation of estimation uncertainty and its implications for interdependency learning. For nonlinear systems, the dissertation introduces graph attention-based learning with a predefined candidate graph structure, establishing theoretical relationships between learned attention coefficients and Jacobian-based interdependencies. It further develops a complementary framework for learning nonlinear interdependencies without requiring a predefined graph skeleton, where the downstream task of root cause analysis is explored. The proposed methods are evaluated on synthetic and industrial datasets, demonstrating their utility for decentralized prediction and interdependency characterization.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EDecentralized Learning of Interdependencies for Multi-Component Dynamic Systems\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Decentralized Learning of Interdependencies for Multi-Component Dynamic Systems"}],"uid":"27707","created_gmt":"2026-10-28 14:58:35","changed_gmt":"2026-10-28 14:59:14","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-10T10:00:00-05:00","event_time_end":"2026-11-10T12:00:00-05:00","event_time_end_last":"2026-11-10T12:00:00-05:00","gmt_time_start":"2026-11-10 15:00:00","gmt_time_end":"2026-11-10 17:00:00","gmt_time_end_last":"2026-11-10 17:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Virtual via Zoom ","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693571":{"#nid":"693571","#data":{"type":"event","title":"PhD Defense by Christopher Kraemer","body":[{"value":"\u003Cp\u003ETitle: Democratization of battery-less and sustainable computing systems\u003Cbr\u003EDate: Wednesday, November 11th, 2026\u003Cbr\u003ETime: 10am - 12pm Eastern Time\u003Cbr\u003EWhere: Coda C1215 Midtown\u003Cbr\u003EOnline: Link\u003C\/p\u003E\u003Cp\u003E\u003Cbr\u003EChristopher Kraemer\u003Cbr\u003EPhD Candidate\u003Cbr\u003ESchool of Computer Science\u003Cbr\u003ECollege of Computing\u003Cbr\u003EGeorgia Institute of Technology\u003C\/p\u003E\u003Cp\u003ECommittee\u003Cbr\u003EDr. Josiah Hester(Advisor) - School of Computer Science, Georgia Institute of Technology\u003Cbr\u003EDr. Ellen Zegura - School of Computer Science, Georgia Institute of Technology\u003Cbr\u003EDr. \u0026nbsp;Umakishore Ramachandran, School of Computer Science, Georgia Institute of Technology\u003Cbr\u003EDr. Alex Adams - School of Interactive Computing, Georgia Institute of Technology\u003Cbr\u003EDr. Thomas Ball - Honorary Professor, Lancaster University \u0026amp; Affiliate Faculty, University of Washington\u003C\/p\u003E\u003Cp\u003EAbstract\u003C\/p\u003E\u003Cp\u003EThree pillars of democratization are equity, access, and agency. An equitable system lowers the barrier to entry for novice users and programmers. First, I show equity through Battery-free MakeCode, a compiler modification to the popular education tool Microsoft\u2019s MakeCode for micro:bit. This compiler modification analyses, reorganizes, and inserts code into a novice\u2019s program so that even someone who is just learning how to code can make a battery-free device with the BBC micro:bit. Second, access means expanding battery-less computing to hobbyists, makers, and researchers. In my paper User-directed Assembly Code Transformations Enabling Efficient Batteryless Arduino Applications, I developed a low-level binary rewriting tool to enable battery-free computing for Arduino users. This allows Arduino users to make an intermittent device with a wide array of off-the-shelf hardware.

This means that the vast majority of people on the AD continuum are in the early stages where the pathology accumulates before substantial functional impairments. The locus coeruleus (LC), the brain\u2019s principal source of norepinephrine (NE), is among the earliest regions affected by tau pathology in AD and plays a central role in regulating cognition, arousal, and brain-network function. Neuromelanin-sensitive magnetic resonance imaging (NM-MRI) enables noninvasive assessment of the LC, offering a promising biomarker of disease-related changes and an anatomical reference for multimodal imaging. However, prolonged acquisition times and limited availability of NM-MRI in large neuroimaging cohorts constrain its broader application. This dissertation aims to improve the accessibility and reliability of NM-MRI of the LC through deep learning (DL) and characterize the LC\u2013NE system\u2019s response to pharmacological noradrenergic modulation in mild cognitive impairment (MCI). We develop DL frameworks to overcome key limitations in LC imaging, enabling accelerated NM-MRI acquisition that preserves LC contrast-based imaging biomarkers and extending LC localization to routinely acquired structural MRI through generative synthesis. Beyond conventional image quality metrics, these methods are evaluated for their ability to capture disease-related differences and support individualized LC localization for functional and diffusion MRI analyses. We further employ a multimodal approach to characterize the effects of noradrenergic modulation on LC contrast, functional connectivity, and neurofluid-associated physiology, integrating these imaging measures with AD-related biomarkers and cognitive function to provide a more comprehensive assessment of the LC-NE system. Together, these efforts aim to broaden and advance the use of LC imaging in clinical research while providing new insights into the structural and functional responses of the LC-NE system to noradrenergic modulation in MCI. These advances can facilitate the development of imaging biomarkers and support the evaluation of emerging therapeutic strategies for AD.\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EQuantitative Analysis of the Locus Coeruleus in Alzheimer\u0027s Disease Using Multimodal MRI\u003Cbr\u003E\u003Cbr\u003E\u0026nbsp;\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Quantitative Analysis of the Locus Coeruleus in Alzheimer\u0027s Disease Using Multimodal MRI"}],"uid":"27707","created_gmt":"2026-10-27 16:00:18","changed_gmt":"2026-10-27 16:00:53","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-09T11:00:13-05:00","event_time_end":"2026-11-09T13:00:00-05:00","event_time_end_last":"2026-11-09T13:00:00-05:00","gmt_time_start":"2026-11-09 16:00:13","gmt_time_end":"2026-11-09 18:00:00","gmt_time_end_last":"2026-11-09 18:00:00","rrule":null,"timezone":"America\/New_York"},"location":"N147 - HSRB II ","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693506":{"#nid":"693506","#data":{"type":"event","title":"PhD Proposal by Chih-Yu Lo","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003ESchool of Physics Thesis Proposal\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EChih-Yu Lo\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EAdvisor:\u0026nbsp;

Risk equations based on chronological age and conventional clinical factors cannot fully capture accumulated CV injury among people with similar profiles. People classified as low or borderline risk may still experience major adverse cardiovascular events (MACE), revealing risk heterogeneity that current approaches do not fully resolve. CV biological aging (CV-Age) is a multidimensional process shaped by intrinsic biology and lifetime environmental and psychosocial exposures. It may be reflected in cumulative subclinical injury, inflammation, fibrosis, and vascular remodeling. In this proposal, CV-Age is operationalized as an imaging-derived age estimate based on age-associated features quantified from medical images. Routine chest computed tomography (CT) and retinal photography offer complementary views of cardiovascular biology: CT captures macrovascular, structural, and cardiometabolic features, whereas retinal photographs visualize microvascular structure. Explainable artificial intelligence (AI) can quantify aging patterns from images already acquired in clinical care. The objective is to develop and evaluate CT-derived CV-Age and retinal-derived CV-Age independently, then determine whether their integration adds information beyond either modality alone. The central hypothesis is that these measures capture distinct, potentially complementary manifestations of cardiovascular aging that are associated with MACE. Aim 1 will develop CT-derived CV-Age from chest CT radiomics and evaluate its association with future MACE. Aim 2 will develop retinal-derived CV-Age from fundus oculomics and evaluate its association with future MACE. Aim 3 will test whether integrating the independently evaluated measures improves age estimation or MACE risk stratification in cohorts with linked CT and retinal imaging. This proposal will determine whether either modality or their combination adds incremental clinical value to existing risk algorithms. By transforming underused routine-image data into an individualized description of cardiovascular aging, findings from this proposal could support earlier and more personalized risk recognition.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EMultimodal Imaging Biomarkers of Cardiovascular Biological Aging\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Multimodal Imaging Biomarkers of Cardiovascular Biological Aging"}],"uid":"27707","created_gmt":"2026-10-27 12:21:15","changed_gmt":"2026-10-27 12:26:41","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-12-07T16:00:00-05:00","event_time_end":"2026-12-07T18:00:00-05:00","event_time_end_last":"2026-12-07T18:00:00-05:00","gmt_time_start":"2026-12-07 21:00:00","gmt_time_end":"2026-12-07 23:00:00","gmt_time_end_last":"2026-12-07 23:00:00","rrule":null,"timezone":"America\/New_York"},"location":"HSRB2-N657","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693504":{"#nid":"693504","#data":{"type":"event","title":"PhD Defense by Christian Douglas","body":[{"value":"\u003Cp\u003ESchool of Civil and Environmental Engineering\u003C\/p\u003E\u003Cp\u003EPh.D. Thesis Defense Announcement\u003C\/p\u003E\u003Cp\u003EExamining the Role Of Automation Technology in Transportation Interactions: How Vehicle Affordances Affect Equity and User Well-Being\u003C\/p\u003E\u003Cp\u003EBy: Christian Douglas\u003C\/p\u003E\u003Cp\u003EMolecular Sciences and Engineering 1222\u003Cbr\u003E\u003Ca href=\u0022https:\/\/gatech.zoom.us\/j\/94927419491\u0022\u003Ehttps:\/\/gatech.zoom.us\/j\/94927419491\u003C\/a\u003E\u003C\/p\u003E\u003Cp\u003E2026-11-13 11:00 AM ET\u003C\/p\u003E\u003Cp\u003EDr. Adjo Amekudzi-Kennedy, Dr. Sof\u00eda P\u00e9rez-Guzm\u00e1n, Dr. David Ederer, Dr. Mark Tschaepe\u003C\/p\u003E\u003Cp\u003EAutonomous vehicles (AVs) and vehicle automation technology come in all shapes and forms. Vehicle producers are including advanced technology in new vehicles, and ride-hailing companies are deploying AVs in cities across the United States. As such, it is crucial to look across all levels of automation to evaluate the usability of vehicle automation technology and AVs. This research examines the ability of transportation features and technology to provide affordances (i.e., aspects of the environment providing functionality) to a diverse set of potential users. This work employs a variety of methodological approaches to answer the central research question of how vehicle automation technology provide affordances to human drivers. This mixed-methods, interdisciplinary research addresses this fundamental and guiding research question by (1) advancing a disciplinary understanding of equitable transportation technology; (2) gathering the insight and experience of vehicle users, designers, and regulators; and (3) utilizing a hypothetical lane reduction scenario to explore the potential affordances, and disaffordances, resulting from interactions between vehicles at varying levels of automation. Findings can be used to advise vehicle producers on inclusive vehicle design practices, inform policy guiding nascent vehicle technology, and help future researchers understand the direction these new technologies are going and the threats they can pose to individual safety and well-being.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EExamining the Role Of Automation Technology in Transportation Interactions: How Vehicle Affordances Affect Equity and User Well-Being\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Examining the Role Of Automation Technology in Transportation Interactions: How Vehicle Affordances Affect Equity and User Well-Being"}],"uid":"27707","created_gmt":"2026-10-27 12:11:38","changed_gmt":"2026-10-27 12:12:14","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-13T11:00:00-05:00","event_time_end":"2026-11-13T13:00:00-05:00","event_time_end_last":"2026-11-13T13:00:00-05:00","gmt_time_start":"2026-11-13 16:00:00","gmt_time_end":"2026-11-13 18:00:00","gmt_time_end_last":"2026-11-13 18:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Molecular Sciences and Engineering 1222","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693503":{"#nid":"693503","#data":{"type":"event","title":"PhD Defense by Yosia Nurhan","body":[{"value":"\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ETitle:\u0026nbsp;\u003C\/strong\u003EModeling crime response to deterrence and positive incentives: existence of solutions, optimal policies, and fairness\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EDate:\u0026nbsp;\u003C\/strong\u003ENovember 13th\u0026nbsp;, 2026\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ETime:\u0026nbsp;\u003C\/strong\u003E11 AM - 1 PM, EST\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ELocation\u003C\/strong\u003E: Guggenheim 246\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EZoom link:\u0026nbsp;\u003C\/strong\u003E\u003Ca href=\u0022https:\/\/nam12.safelinks.protection.outlook.com\/?url=https%3A%2F%2Fgatech.zoom.us%2Fj%2F7854428648%3Fpwd%3DMjkvcHRXY2lqZVJXRS9PS1Y4dEVkZz09\u0026amp;data=05%7C02%7Cannouncements%40grad.gatech.edu%7C1a4b3b3001c24f3e4e8908df341e60b3%7C482198bbae7b4b258b7a6d7f32faa083%7C1%7C0%7C639286977259925257%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C\u0026amp;sdata=fdWYfspLNVHuzQ1hKXwdVeJ8GNbTSXCLOnx%2F%2FbPLYr0%3D\u0026amp;reserved=0\u0022\u003E\u003Cstrong\u003Ehttps:\/\/gatech.zoom.us\/j\/7854428648?pwd=MjkvcHRXY2lqZVJXRS9PS1Y4dEVkZz09\u003C\/strong\u003E\u003C\/a\u003E\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECommittee:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EDr. Martin Short (Advisor)\u003C\/p\u003E\u003Cp\u003EDr. Sung Ha Kang\u003C\/p\u003E\u003Cp\u003EDr. Wenjing Liao\u003C\/p\u003E\u003Cp\u003EDr. Haomin Zhou\u003C\/p\u003E\u003Cp\u003EDr. George Mohler\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EAbstract:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EIn this work we study a model in which rational agents decide whether or not to commit crime based on a utility calculation, influenced by a judge who sets a society-wide threshold corresponding to the likelihood of an individual being found guilty and a legislator who sets a society-wide punishment level. We first study how the overall crime rate is influenced by the judge\u0027s threshold and the legislator\u0027s punishment level, propose an objective function for the judge and legislator to minimize, and study the optimal threshold and punishment levels for this objective. \u0026nbsp;We then consider the case in which the overall society is subdivided into multiple groups with varying characteristics, introducing a constraint on fairness in treatment between the groups. \u0026nbsp;We study how an optimal threshold and punishment level might be chosen under this fairness constraint, what ramifications the constraints have on outcomes for individuals, and under what circumstances the constrained optimum agrees with the unconstrained optimum. Then we introduce a new lever for the justice system in the form of positive incentives for the agents: first as a subsidy and then later as a program motivated by the Trusted Traveler Program where agents can opt in or opt out from taking the positive incentive in exchange for some extra initial investigation. We then study the optimal threshold, punishment level, and positive incentive level that achieves the justice system\u0027s objective for both unlimited budget and a budget constraint\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EModeling crime response to deterrence and positive incentives: existence of solutions, optimal policies, and fairness\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Modeling crime response to deterrence and positive incentives: existence of solutions, optimal policies, and fairness"}],"uid":"27707","created_gmt":"2026-10-27 12:09:44","changed_gmt":"2026-10-27 12:10:20","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-13T11:00:00-05:00","event_time_end":"2026-11-13T13:00:00-05:00","event_time_end_last":"2026-11-13T13:00:00-05:00","gmt_time_start":"2026-11-13 16:00:00","gmt_time_end":"2026-11-13 18:00:00","gmt_time_end_last":"2026-11-13 18:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Guggenheim 246","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693485":{"#nid":"693485","#data":{"type":"event","title":"MS Defense by Burke Thompson","body":[{"value":"\u003Cp\u003EBurke Thompson\u003Cbr\u003EBME MS Thesis Defense Presentation\u003Cbr\u003E\u003Cstrong\u003EDate\u003C\/strong\u003E: 2026-11-06\u003Cbr\u003E\u003Cstrong\u003ETime\u003C\/strong\u003E: 3:00-4:00 PM\u003Cbr\u003E\u003Cstrong\u003ELocation \/ Meeting Link\u003C\/strong\u003E: IC 215\/ \u003Ca href=\u0022https:\/\/teams.microsoft.com\/meet\/253067914699016?p=MknQtGe58qjnz7MnD2\u0022\u003Ehttps:\/\/teams.microsoft.com\/meet\/253067914699016?p=MknQtGe58qjnz7MnD2\u003C\/a\u003E\u003Cbr\u003E\u003Cbr\u003E\u003Cstrong\u003ECommittee Members:\u003C\/strong\u003E\u003Cbr\u003EProf. Lakshmi Dasi; Dr. Thangam Natarajan; Prof. Rudolph Gleason\u003Cbr\u003E\u003Cbr\u003E\u003Cbr\u003E\u003Cstrong\u003ETitle\u003C\/strong\u003E: Multifidelity Hemodynamic Frameworks for Patient-Specific Risk Assessment in Transcatheter Cardiac Interventions and Congenital Heart Defects\u003Cbr\u003E\u003Cbr\u003E\u003Cstrong\u003EAbstract:\u003C\/strong\u003E\u003Cbr\u003ECardiovascular disease (CVD) is the leading cause of death in the United States, accounting for more than 1 million deaths annually and upwards of $400 billion dollars in associated annual costs. Computational modelling tools such as Finite Element Analysis, Computational Fluid Dynamics, and Fluid-Structure Interaction offer relatively inexpensive and noninvasive methods to investigate the relationships between CVD etiology and underlying physiology and biomechanics. In the clinic, modelling tools can be employed to optimize clinical management or to plan interventional procedures, improving patient outcomes in the setting of CVD. In this work, novel multifidelity modelling frameworks for pre-procedural risk stratification of transcatheter valve replacement (TAVR) and anomalous aortic origin of the coronary arteries (AAOCA) are developed and applied retrospectively to model outcomes in real patient cohorts. A one-way fluid-structure interaction pipeline is used to correlate post-TAVR hemodynamics with hypoattenuated leaflet thickening (HALT) in a cohort of 23 patients, and a tunable one-dimensional fluid-structure interaction model of anomalous aortic origin of the coronary arteries is employed to predict deformation dynamics and flow restriction in 7 AAOCA patients. These frameworks take as input readily available pre-procedural clinical data and provide insight into post-procedural biomechanical state, providing the framework for future clinical risk-stratification and procedural pipelines.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EMultifidelity Hemodynamic Frameworks for Patient-Specific Risk Assessment in Transcatheter Cardiac Interventions and Congenital Heart Defects\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Multifidelity Hemodynamic Frameworks for Patient-Specific Risk Assessment in Transcatheter Cardiac Interventions and Congenital Heart Defects"}],"uid":"27707","created_gmt":"2026-10-26 17:06:18","changed_gmt":"2026-10-26 17:06:54","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-06T15:00:00-05:00","event_time_end":"2026-11-06T16:00:00-05:00","event_time_end_last":"2026-11-06T16:00:00-05:00","gmt_time_start":"2026-11-06 20:00:00","gmt_time_end":"2026-11-06 21:00:00","gmt_time_end_last":"2026-11-06 21:00:00","rrule":null,"timezone":"America\/New_York"},"location":"IC 215","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"111531","name":"ms defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693484":{"#nid":"693484","#data":{"type":"event","title":"PhD Defense by Selim Furkan Tekin","body":[{"value":"\u003Cp\u003EDear faculty members and fellow students,\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EYou are cordially invited to my PhD thesis defense on Monday, November 23rd.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ETitle:\u0026nbsp;\u003C\/strong\u003EAdaptive and Robust Model Fusion for Multi-Modal Learning Systems\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EDate:\u0026nbsp;\u003C\/strong\u003EMonday,\u003Cstrong\u003E\u0026nbsp;\u003C\/strong\u003ENovember 23, 2026\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ETime:\u0026nbsp;\u003C\/strong\u003E1:00 PM - 3:00 PM Eastern Time (US)\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ELocation:\u0026nbsp;\u003C\/strong\u003EKACB 3402\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EVirtual (Zoom):\u0026nbsp;\u003C\/strong\u003E\u003Ca href=\u0022https:\/\/nam12.safelinks.protection.outlook.com\/?url=https%3A%2F%2Fgatech.zoom.us%2Fj%2F94537626884%3Fpwd%3Df2aDUdkbH2u8p6w9oLP0zMBdv6CJCN.1\u0026amp;data=05%7C02%7Cannouncements%40grad.gatech.edu%7Cd2b568c3ba464970d91008df330be8ae%7C482198bbae7b4b258b7a6d7f32faa083%7C1%7C0%7C639285798403191466%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C\u0026amp;sdata=W3V%2Bt%2BoccpOE1%2Fld8p07z75M4XqgVQb3329fvEkxfv0%3D\u0026amp;reserved=0\u0022\u003Ehttps:\/\/gatech.zoom.us\/j\/94537626884?pwd=f2aDUdkbH2u8p6w9oLP0zMBdv6CJCN.1\u003C\/a\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ESelim\u0026nbsp;Furkan\u0026nbsp;Tekin\u003C\/strong\u003E\u003Cbr\u003EPh.D. Candidate in Computer Science\u003Cbr\u003ESchool of Computer Science\u003Cbr\u003EGeorgia Institute of Technology\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECommittee members:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E1.

However, based on the benchmark studies and model release announcements revealed that even the newest released or largest models tend to carry some weaknesses despite the unique strengths, indicating no one model can be the persistent winner in generalization performance across all tasks. Complementing this, user-generated queries tend to have varying complexity and involve simple common knowledge tasks or complex reasoning or specific domain knowledge. For simple queries involving superficial understanding, smaller models can do a perfect job at a minimal cost. Hence, there is a challenge in adequately choosing a model or group of models based on the client-user constraints and the downstream learning tasks at hand. This dissertation is dedicated to tackling the above grand challenges by designing and developing innovative methodologies, algorithms, and optimizations in selecting, refining, and integrating multiple gen-AI models.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EOur research began with a comprehensive empirical study, which led to three observations: First, in classical few-shot learning methods, ensemble gains come largely from two channels: structural (model architecture) and geometric (distance metric) diversity\u2013motivating heterogeneous model selection. We later found that the same holds for modern few-shot learners such as LLMs and VLMs. Second, larger heterogeneous ensemble teams may not necessarily offer better generalization performance, because some members make redundant predictions that add inference cost without adding new information. Third, the language models and vision models require different multi-stage representation learning to effectively capture duplicated learning capabilities. Motivated by these observations, we have made four novel and fundamental contributions:\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003EFirst\u003C\/em\u003E, we have developed a novel diversity computation framework that can be tailored for both language and vision representation learning to capture the disagreement correlation among multiple gen-AI models (LLMs, LVMs, and VLMs).\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003ESecond\u003C\/em\u003E, we have designed the first of its kind diversity-optimized ensemble pruning framework, which supports LLM and VLM ensemble pruning. The pruning utilizes genetic search optimization on introduced metrics: the focal-diversity metric and focal Central Kernel Alignment (CKA) to identify informative complementary representations for vision-language ensemble pruning.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003EThird\u003C\/em\u003E, we study learning-to-combine architectures and develop two diversity-optimized ensemble fusion methods. The first is a supervised approach that uses diversity-driven pruning to select an ensemble team offline and then learns to fuse its outputs, achieving stronger generalization than state-of-the-art methods. The second selects the team and fuses outputs dynamically at inference time, using a two-stage reinforcement learning framework.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003EFinally\u003C\/em\u003E, we address model routing and fusion through joint optimization, learning how to \u003Cem\u003Eselect\u003C\/em\u003E, \u003Cem\u003Ereason\u003C\/em\u003E, and \u003Cem\u003Erefine\u003C\/em\u003E\u0026nbsp;across multiple VLMs. We develop two routing systems trained with reinforcement learning. The first starts from prior beliefs about each VLM\u2019s performance: a routing policy chooses which model to consult, and a fusion policy decides whether to keep consulting or answer. The second targets physical reasoning in real-world scenes: it matches the skills a query requires to each VLM\u2019s perception strengths, routes to models in sequence, and refines a lightweight policy using critiques from a tool-augmented critic that extracts visual clues. In both lines of work, we compare our approaches against widely used AI chatbots and show that our approaches succeed in real-world scenarios where existing models often fail.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003ECollectively, these contributions offer new ways to build teams of diverse AI models that reason together, combine their outputs, and verify their answers.

It\u2019s projected to affect 112 million people by 2040, and 60-67% of the glaucomatous population are women. While elevated intraocular pressure (IOP) remains a major risk factor associated with developing glaucoma, recent work suggests that menopause is a sex-specific factor associated with glaucoma.\u003C\/p\u003E\u003Cp\u003EStudies have found that menopause had a linear association with the timing of glaucoma diagnosis, and that early-onset menopause increases the risk of developing glaucoma later in life. Menopause has also been shown to increase intraocular pressure (IOP) \u2013 the only modifiable risk factor for glaucoma. However, the role of menopause in glaucoma development is still not well understood. To address this gap, this work characterizes the potential impact of early-onset menopause on IOP, eye biomechanics, and transcriptomic changes within the conventional outflow pathway, which is largely responsible for regulating IOP.\u003C\/p\u003E\u003Cp\u003EIn a preclinical approach we modeled early-onset menopause via ovariectomy (OVX). In \u003Cstrong\u003EAim 1\u003C\/strong\u003E, we focused on determining the impact of early-onset menopause over time on IOP and aqueous humor outflow facility, which is how easily fluid can exit the eye. In \u003Cstrong\u003EAim 2,\u003C\/strong\u003E we investigated the impact of early-onset menopause on the stiffness of the segmental flow of aqueous humor (low flow and high flow) through the trabecular meshwork (TM), the major tissue regulating aqueous humor outflow within the conventional outflow pathway. Finally, \u003Cstrong\u003EAim 3\u003C\/strong\u003E assessed the transcriptomic changes within the TM induced by early-onset menopause to elucidate potential transcriptional mechanisms driving these functional changes. This work fills an existing gap in the field regarding the effects of early-onset menopause on parameters associated with glaucoma. Thus, in addition to potentially elucidating novel components of glaucoma etiology, this work has the potential to identify therapeutic targets that can lead to new glaucoma treatments in the clinic.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EEarly-onset menopause impact on the biomechanics and transcriptomic profile of the conventional outflow pathway\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Early-onset menopause impact on the biomechanics and transcriptomic profile of the conventional outflow pathway"}],"uid":"27707","created_gmt":"2026-10-26 15:41:09","changed_gmt":"2026-10-26 15:41:46","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-06T10:00:00-05:00","event_time_end":"2026-11-06T11:00:00-05:00","event_time_end_last":"2026-11-06T11:00:00-05:00","gmt_time_start":"2026-11-06 15:00:00","gmt_time_end":"2026-11-06 16:00:00","gmt_time_end_last":"2026-11-06 16:00:00","rrule":null,"timezone":"America\/New_York"},"location":"IBB Suddath Meeting Room #1128","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693452":{"#nid":"693452","#data":{"type":"event","title":"PhD Proposal by Alexander Salmon","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003EAlexander Salmon\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E(Advisors: Prof. Scott Danielsen, Prof. Jason Azoulay, and Prof. Natalie Stingelin)\u003C\/p\u003E\u003Cp\u003EWill propose a doctoral thesis entitled,\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EPost-Polymerization Modification of Aromatic Polymers and their Blends\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003EOn\u003C\/em\u003E\u003C\/p\u003E\u003Cp\u003EFriday, November 6, 2026 from 12:30 pm \u2013 2 pm ET\u003C\/p\u003E\u003Cp\u003EMolecular Science and Engineering Room 1224\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECommittee\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EProf. Scott Danielsen, School of Materials Science and Engineering (Advisor)\u003C\/p\u003E\u003Cp\u003EProf. Jason D.

Unfortunately, these same properties prevent degradation and render their recycling and upcycling exceptionally difficult. Chemical post-polymerization modification (PPM) can produce materials with specialized properties, enabling their use in high-value industries. Unfortunately, traditional methods have limited substrate scope and can degrade the polymer chains. Gold-catalyzed direct C\u2013H bond activation has recently been demonstrated as a method of modifying the aromatic rings of polymers, enabling the attachment of a wide range of pendants. The goal of this thesis is to determine how PPM changes the bulk and interfacial properties during and after synthesis. Aim 1 tests the bulk, determining the effect of pendant size, degree of functionalization, polarity, and intermolecular interactions on the thermomechanical and morphological properties. Aim 2 examines interfaces, testing the hypothesis that alkyl pendant length governs domain size, and mechanical properties in PET\/polyethylene (PE) blends by controlling migration and anchoring. Aim 3 concludes with synthesis, determining whether catalyst structure and milling conditions allow PET chains to be functionalized with minimal degradation. Combined, these three aims will elucidate how PPM can be used to change the properties of aromatic polymers and their blends.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EPost-Polymerization Modification of

expansion of electric mobility, grid-scale energy storage, and portable electronics necessitates next-generation rechargeable batteries that fundamentally transcend the safety risks, critical-mineral supply vulnerabilities, and high manufacturing costs of incumbent technologies. Conventional lithium-ion batteries rely on volatile, flammable organic carbonate electrolytes and cobalt\/nickel-rich cathodes, presenting severe thermal-runaway hazards and geographic supply-chain dependencies. Consequently, developing earth-abundant, low-cost chemistries is essential for scalable energy storage. Among emerging candidate electrolyte platforms, chloroaluminate systems offer distinctive advantages spanning multiple battery chemistries. Enabled by facile coordination chemistry of chloroaluminates, these electrolytes can be tailored into ambient-temperature ionic liquids, deep eutectic analogues, or low-melting-point inorganic matrices.\u003C\/p\u003E\u003Cp\u003EThis dissertation proposal outlines the investigation and application of chloroaluminate electrolytes across lithium and beyond-Li systems in two primary parts:\u003C\/p\u003E\u003Cul\u003E\u003Cli data-list-item-id=\u0022ece4ee960b865cd79e7585187c06d9abe\u0022\u003E\u003Cp\u003EPart 1: Melt-Infiltrated Chloroaluminate Oxychloride Solid Electrolytes for Li and Na Batteries.\u003C\/p\u003E\u003Cp\u003EConventional solid electrolytes suffer from poor solid\u2013solid interfacial contact and processing constraints that limit active material mass loading. The first part proposes a novel chloroaluminate-based oxychloride inorganic solid electrolyte for both Li and Na systems. Preliminary findings demonstrate high room-temperature ionic conductivity and a modest thermal transition, allowing the electrolyte to behave as a low-viscosity liquid when heated to achieve complete, conformal melt-infiltration into tortuous composite electrodes, solidifying upon cooling into an intimate solid-state conducting network. The proposed research will evaluate the electrochemical performance, scalability, and interfacial chemo mechanics of this system to combine the manufacturing simplicity of liquid cells with the safety and mechanical stability of solid-state architectures.\u003C\/p\u003E\u003C\/li\u003E\u003Cli data-list-item-id=\u0022e3c9cb6bd42534e1fdc795a476525afe1\u0022\u003E\u003Cp\u003EPart 2: Na\u2013Al Hybrid-Ion Batteries.\u003C\/p\u003E\u003Cp\u003ETo transition toward abundant, low-cost battery platforms, the second part proposes a hybrid Na\u2013Al battery chemistry coupling an aluminum metal anode with a dual-ion intercalating open-framework cathode operating in a ternary chloroaluminate ionic liquid electrolyte.

While previous research has extensively investigated the role of cations in these reactions, the contribution of anions remains relatively unexplored. This is primarily due to the limited tools available to directly study the chemical state of anions. Inner-shell x-ray spectroscopy (ISXS) is well-suited for this purpose due to its element selectivity and ability of X-rays to probe electrode materials during in-situ or operando studies. Among these methods, x-ray absorption spectroscopy (XAS) examines the process of generating electron holes, offering insights into the electronic structure and local atomic arrangements of specific elements. Complementarily, x-ray emission spectroscopy (XES) studies the quenching of generated electron holes, providing sensitivity to chemical state, spin state, and ligand environment, making it an essential companion to XAS.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EIn this thesis, I will investigate the mechanism behind oxygen activity (redox) and their effects on the physical property of layered LiCoO2\u0026nbsp;(LCO), LiNixMnyCozO2 (NMCs, x + y + z = 1), \u0026nbsp;and polyanion-based LiFePO4\u0026nbsp;(LFP) cathode material for LIBs. First, the onset of oxygen reactions in LCO and NMC cathodes is identified using a combination of several ISXS methods, followed by an investigation into the resulting changes in their structure and physical properties. Next, the formation of metastable phase during the charge process of LFP is qualitatively studied using linear combination analysis of iron K-edge XAS. The role of anions, specifically phosphorus and oxygen, in LFP is then investigated during charging using phosphorus K emissions and oxygen K-edge absorption, respectively. Finally, K\u03b2 XES is explored as a probe for monitoring the chemical state of transition metals and their covalency with oxygen during LIB cycling, with its results benchmarked against those obtained using XAS.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cstrong\u003ERevealing Anion Contributions in Lithium-Ion Batteries using Inner-Shell X-Ray Spectroscopy\u003C\/strong\u003E\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Revealing Anion Contributions in Lithium-Ion Batteries using Inner-Shell X-Ray Spectroscopy"}],"uid":"27707","created_gmt":"2026-10-23 17:57:33","changed_gmt":"2026-10-23 17:58:02","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-06T12:00:00-05:00","event_time_end":"2026-11-06T14:00:07-05:00","event_time_end_last":"2026-11-06T14:00:07-05:00","gmt_time_start":"2026-11-06 17:00:00","gmt_time_end":"2026-11-06 19:00:07","gmt_time_end_last":"2026-11-06 19:00:07","rrule":null,"timezone":"America\/New_York"},"location":"Callaway Manufacturing Research Building \u2013 Auditorium 101 or Virtually via Microsoft Teams","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693421":{"#nid":"693421","#data":{"type":"event","title":"PhD Proposal by Duncan Waanders","body":[{"value":"\u003Cp\u003EStudent Name: Duncan Waanders\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EAdvisor: Dr. Juergen Rauleder\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EMilestone: PhD Thesis Proposal\u003Cbr\u003E\u003Cbr\u003EDegree Program: Aerospace Engineering\u003Cbr\u003E\u003Cbr\u003ETitle: Improved Rotor Modeling for Complex Aerodynamic Interactions with the Lattice Boltzmann Method\u003Cbr\u003E\u003Cbr\u003EAbstract: Vertical take-off and landing (VTOL) rotorcraft offer unmatched operational flexibility, but optimizing their performance requires accurately modeling rotorcraft aerodynamic interactions. This task is significantly complicated by emerging multirotor configurations and challenging operational environments, such as ship airwakes and urban flow fields. Analyzing these multi-source interactional phenomena is hindered by current computational limitations, as high-fidelity computational fluid dynamics (CFD) is prohibitively expensive and low-fidelity methods simplify critical flow physics. This gap motivates the development of advanced mid-fidelity modeling approaches, as delivering computationally efficient, rapid-turnaround solutions is essential to enable large-scale optimization, comprehensive parameter sweeps, and real-time flight simulator integration. This proposed thesis will present the development of a new rotor model based on the actuator line method (ALM) within a mid-fidelity GPU-accelerated Lattice Boltzmann Method (LBM) CFD framework. The new LBM-ALM approach was shown to correlate well with published experimental data and high-fidelity CFD for an isolated single-rotor in hover. The approach was then validated for ship-rotor dynamic interface simulations against sub-scale experimental data and compared to an existing LBM-actuator disk method (ADM) framework, confirming an increase in interactional aerodynamic fidelity. Finally, both the LBM-ALM and LBM-ADM frameworks were validated with excellent correlation to an experimental multirotor hovering in ground effect. The combined results established that the developed framework provides a robust, scalable platform for accurate and computationally efficient interactional aerodynamic analysis.\u003Cbr\u003E\u003Cbr\u003EDate and time: 2026-10-29, 10:00\u003Cbr\u003E\u003Cbr\u003ELocation: Skiles 270\u003Cbr\u003E\u003Cbr\u003ECommittee:\u003Cbr\u003EDr. Juergen Rauleder (advisor), School of Aerospace Engineering\u003Cbr\u003EDr. Marilyn Smith, School of Aerospace Engineering\u003Cbr\u003EDr. Beckett Zhou, School of Aerospace Engineering\u003Cbr\u003EDr. Alex Moushegian, US Navy - NAWCAD\u003Cbr\u003E,\u0026nbsp;\u003Cbr\u003E\u003Cbr\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EImproved Rotor Modeling for Complex Aerodynamic Interactions with the Lattice Boltzmann Method\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Improved Rotor Modeling for Complex Aerodynamic Interactions with the Lattice Boltzmann Method"}],"uid":"27707","created_gmt":"2026-10-23 12:52:54","changed_gmt":"2026-10-23 12:54:05","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-10-29T10:00:00-04:00","event_time_end":"2026-10-30T12:00:00-04:00","event_time_end_last":"2026-10-30T12:00:00-04:00","gmt_time_start":"2026-10-29 14:00:00","gmt_time_end":"2026-10-30 16:00:00","gmt_time_end_last":"2026-10-30 16:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Skiles 270","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693402":{"#nid":"693402","#data":{"type":"event","title":"PhD Defense by Rebecca Storey ","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003EName: Rebecca Storey\u0026nbsp;\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ESchool of Psychological and Brain Sciences \u2013 Ph.D.\u0026nbsp;Dissertation Defense Meeting\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EDate:\u003C\/strong\u003E\u0026nbsp;Thursday, November 12th, 2026\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ETime:\u003C\/strong\u003E\u0026nbsp;4:00 pm - 6:00 pm\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ETeams link:\u0026nbsp;\u003C\/strong\u003E\u003Ca href=\u0022https:\/\/teams.microsoft.com\/meet\/2302645032310995?p=uqZfljEzJxXeunGtBe\u0022 target=\u0022_blank\u0022 title=\u0022https:\/\/teams.microsoft.com\/meet\/2302645032310995?p=uqZfljEzJxXeunGtBe\u0022\u003EJoin here\u0026nbsp;\u003C\/a\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003E\u0026nbsp;\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EDissertation Chair\/Advisor:\u003C\/strong\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EPhillip L.

To explore this possibility, I adopted an aptitude-treatment interaction (ATI) approach to test whether generative AI acts as a treatment that modifies the influence of cognitive and motivational aptitudes on creative problem-solving (CPS) performance. A sample of 111 undergraduate students participated in a three-part study that consisted of: 1) a survey measuring motivational traits and readiness to leverage generative AI; 2) cognitive ability tests; and 3) working on CPS tasks without and then with access to ChatGPT. For each task, participants read a scenario and prepared a short PowerPoint presentation of their solution. The results revealed three findings. First, solutions developed in the experimental condition (Internet plus ChatGPT) were rated higher than those in the control condition (Internet-use only), \u003Cem\u003Ed\u003C\/em\u003E = .72. Pilot data suggest the CPS tasks are similar in difficulty; however, because the tasks differed across conditions, these ratings cannot support claims that performance improved. Second, while none of the motivational aptitudes predicted performance in either condition, cognitive ability positively predicted performance in the control condition, B = .25, but not in the experimental condition, B = .07. Instead, generative AI readiness predicted performance in the experimental condition, B = .21, though the relationship was small. To better understand what differentiated high from low performance in the experimental condition, I reviewed screen recordings of the top and bottom performers to see how they used ChatGPT. High performers distinguished themselves by correctly anticipating that ChatGPT could adequately complete the task on its own. Those participants typed the full prompt into ChatGPT and then reallocated cognitive resources away from on-task activities (e.g., information gathering, ideation, reasoning) and put them toward self-regulatory activities that ChatGPT could not replace (e.g., managing time, modifying output, designing the presentation, ensuring it aligned with task expectations). This strategy is likely not optimal across all situations. Rather than viewing performance as a two-way aptitude-treatment interaction, performance may be better described as a three-way interaction that includes task complexity. That said, findings from the present study suggest that for relatively straightforward tasks requiring only general knowledge, generative AI may act as an equalizer, disproportionately supporting lower-ability individuals.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003ECreative Problem-Solving with Generative AI: An Examination of Aptitude-Treatment Interactions\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Creative Problem-Solving with Generative AI: An Examination of Aptitude-Treatment Interactions"}],"uid":"27707","created_gmt":"2026-10-22 16:19:35","changed_gmt":"2026-10-22 16:20:21","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-12T16:00:00-05:00","event_time_end":"2026-11-12T18:00:00-05:00","event_time_end_last":"2026-11-12T18:00:00-05:00","gmt_time_start":"2026-11-12 21:00:00","gmt_time_end":"2026-11-12 23:00:00","gmt_time_end_last":"2026-11-12 23:00:00","rrule":null,"timezone":"America\/New_York"},"location":"TEAMS","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693391":{"#nid":"693391","#data":{"type":"event","title":"PhD Defense by Jiong Yang","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003ETitle\u003C\/strong\u003E: Efficient and Trusted Approximate Model Counting\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EDate\u003C\/strong\u003E: Friday, October 30th, 2026\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ETime\u003C\/strong\u003E: 1:00 - 3:00 PM ET\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ELocation\u003C\/strong\u003E: Klaus 3100\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EZoom\u003C\/strong\u003E:\u0026nbsp;\u003Ca href=\u0022https:\/\/nam12.safelinks.protection.outlook.com\/?url=https%3A%2F%2Fgatech.zoom.us%2Fj%2F92641944955\u0026amp;data=05%7C02%7Cannouncements%40grad.gatech.edu%7Ca3c246bd767d4931f8ea08df2ee2b658%7C482198bbae7b4b258b7a6d7f32faa083%7C1%7C0%7C639281223419915288%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C\u0026amp;sdata=fce8OTMcNdeY7T5LeUWi54tFdiHALkNi7C9F588qUok%3D\u0026amp;reserved=0\u0022 target=\u0022_blank\u0022 title=\u0022https:\/\/gatech.zoom.us\/j\/92641944955\u0022\u003Ehttps:\/\/gatech.zoom.us\/j\/92641944955\u003C\/a\u003E\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EJiong Yang\u003C\/strong\u003E\u003Cbr\u003EPh.D. Student\u003C\/p\u003E\u003Cp\u003ESchool of Computer Science\u003C\/p\u003E\u003Cp\u003ECollege of Computing\u003C\/p\u003E\u003Cp\u003EGeorgia Institute of Technology\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022https:\/\/nam12.safelinks.protection.outlook.com\/?url=https%3A%2F%2Fal-jiongyang.github.io%2F\u0026amp;data=05%7C02%7Cannouncements%40grad.gatech.edu%7Ca3c246bd767d4931f8ea08df2ee2b658%7C482198bbae7b4b258b7a6d7f32faa083%7C1%7C0%7C639281223419944608%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C\u0026amp;sdata=y6vfUujcotKkhqM03nSfMiNWg%2FceV%2B3jg9bKSl4MSUA%3D\u0026amp;reserved=0\u0022 target=\u0022_blank\u0022 title=\u0022Original URL: https:\/\/al-jiongyang.github.io\/.

It is a fundamental problem in computer science, with applications in probabilistic inference, neural-network verification, computational biology, and quantum computing. In pursuit of ever-greater scalability in these applications, we study randomized approximate model counting, which trades precision for efficiency. These techniques provide an (\u03b5, \u03b4)-guarantee: with probability at least 1-\u03b4, the estimate lies within a multiplicative factor of 1+\u03b5 of the exact count.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EState-of-the-art approximate counters use hash functions to partition the solution space into cells and estimate the total count from the size of a sampled cell. The practical use of these techniques entails two complementary requirements: computational efficiency for scalability, and assurance of the (\u03b5, \u03b4)-guarantee for dependable results. First, these techniques rely heavily on repeated SAT calls to compute sampled cell sizes, and these expensive calls limit scalability in practice. Second, critical applications such as network reliability and quantitative verification require trust in the returned estimate, whereas it is not immediate that sophisticated implementations retain the probabilistic guarantee established for the abstract algorithms.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EThis thesis advances the efficiency and trustworthiness of hashing-based approximate model counting. To improve efficiency, we develop three complementary algorithmic innovations: rounding-based confidence amplification, single-query cell estimation, and native PB-XOR solving. These innovations reduce the number of independent estimates, the number of SAT calls per estimate, and the cost of individual calls, respectively, while preserving their stated probabilistic guarantees. To establish trust, we develop the first certification pipeline for approximate model counting by combining a formal PAC proof with per-run certificate checking. It verifies that concrete executions satisfy the conditions for the claimed probabilistic guarantee, assuming trusted randomness. Finally, we demonstrate their practical impact in binarized neural network (BNN) verification, where we integrate BNN-specific reasoning into counting and certification to further improve efficiency while maintaining trust in the resulting estimates.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003ECollectively, these contributions constitute a unified advance toward more practical and dependable approximate model counting for demanding applications. As a concrete demonstration, the resulting approach achieves a 113\u00d7 speedup over the previous state of the art in quantitative BNN verification. Among the instances successfully solved by the counter, 86% are fully certified within the reported resource limits.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EEfficient and Trusted Approximate Model Counting\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Efficient and Trusted Approximate Model Counting"}],"uid":"27707","created_gmt":"2026-10-22 13:39:16","changed_gmt":"2026-10-22 13:39:58","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-10-30T13:00:00-04:00","event_time_end":"2026-10-30T15:00:00-04:00","event_time_end_last":"2026-10-30T15:00:00-04:00","gmt_time_start":"2026-10-30 17:00:00","gmt_time_end":"2026-10-30 19:00:00","gmt_time_end_last":"2026-10-30 19:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Klaus 3100","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693390":{"#nid":"693390","#data":{"type":"event","title":"PhD Proposal by Sarah Kim","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003EName: Sarah Kim\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ESchool of Psychological and Brain Sciences \u2013 Ph.D. Dissertation Proposal Meeting\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EDate:\u003C\/strong\u003E\u0026nbsp;Thursday, October 29th, 2026\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ETime:\u003C\/strong\u003E\u0026nbsp;2:00 - 4:00PM\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ELocation:\u003C\/strong\u003E\u0026nbsp;\u003Ca href=\u0022https:\/\/nam12.safelinks.protection.outlook.com\/?url=https%3A%2F%2Fgatech.zoom.us%2Fj%2F3889029032\u0026amp;data=05%7C02%7Cannouncements%40grad.gatech.edu%7C80c6247038764b8f68cf08df2ee99f57%7C482198bbae7b4b258b7a6d7f32faa083%7C1%7C0%7C639281253061406261%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C\u0026amp;sdata=Mfkxf1d0BdxqzbkXcwRe0T2Jf37Ns6z9YpSXEzq1FZw%3D\u0026amp;reserved=0\u0022 title=\u0022Original URL: https:\/\/gatech.zoom.us\/j\/3889029032.

Studies have shown that memory sharing can be influenced by who the listener is. This research extends prior work by exploring potential differences in the content and socioemotional functions of emotional autobiographical memory sharing with robot and human listeners. A mixed-methods study was conducted using a 2 (memory sharing condition: human vs. robot) \u00d7 3 (memory valence: neutral, positive, negative) within-subjects design. Undergraduate participants (N = 58; 51.7% female; age range: 18\u201326 years) recalled and orally shared one neutral, one positive, and one negative memory each with a human listener and with a NAO robot in counterbalanced order. Within each listener condition, the neutral memory was shared first, followed by positive and negative memories in counterbalanced order. The NAO robot was operated through a Wizard-of-Oz procedure in which participants were led to believe the robot responded autonomously.\u0026nbsp; After sharing each memory, participants reported socioemotional experiences (i.e., felt closeness, the listener\u2019s trustworthiness and responsiveness, and interaction quality), memory qualities, and their thoughts about their experience with the human and robot listeners by filling out questionnaires. Content analysis of memory narratives (n = 348) will be performed to capture memory length, event type, internal and external details, use of emotion words, and affective meaning making. Prior to memory sharing, baseline individual difference factors were assessed (e.g., mood, prior experience with AI tools and robots, general trust in people and automated technology, attitudes toward robots, mental health issues, and personality). Mixed-effects models will be conducted to investigate the effects of listener type and memory valence and the interaction effect of these two factors on socioemotional experiences, perceived interaction quality, and self-rated and coded episodic and affective qualities of the memory shared. Differences in event type and memory length will also be examined. Based on the interpersonal process model and existing research, the human listener was expected to be rated higher on closeness, trustworthiness, and responsiveness than the robot listener. Given limited research and mixed findings in available studies, differences in the interaction quality and memory content and qualities between the two listener conditions are exploratory, as are the interaction effects of listener type and memory valence. Thematic analysis will be conducted to analyze open-ended responses to understand listener preferences, reasons behind preferences and memory selection, and perceived purposes of memory sharing. The potential influence of prior experience with and attitudes toward relevant technology will be explored.

To address these limitations, this research develops loss-aware DC formulations, structured AC power-flow restoration methods, and differentiable control policies for distributed slack and PV\/PQ regulation.

A greedy selection then proposes sites subject to the selection constraints described. Additionally, applying spherical harmonic representation provides a single scale-resolved description of the composite score surface and each regional overlay through its degree-power spectrum. It provides the coordinate system in which a placement-induced coverage region can be defined and resolvable. It also helps synthetic data and more future real data products be compared in the spectral domain before deployment, rather than just placements they produce.

Bras\u003C\/p\u003E\u003Cp\u003EPassive microwave remote sensing offers extensive coverage of terrestrial water dynamics, yet reliable retrieval of hydrological variables remains challenging due to the complex interactions among soil, vegetation, and snow within the observed radiometric signal. This dissertation investigates an integrated physical modeling framework grounded in the Maximum Entropy Production (MEP) principle to improve the interpretation of microwave observations across heterogeneous terrestrial environments. Building upon radiative transfer theory and thermodynamically constrained energy partitioning, the MEP framework is examined for the simultaneous retrieval of soil moisture (SM) and vegetation water content (VWC). Evaluations across diverse ecosystems demonstrate strong agreement between retrieved soil moisture and ground observations, with correlations ranging from 0.74 to 0.91 at three SMAP core validation sites. Extensions of the framework reveal seasonal relationships between satellite-derived VWC and live fuel moisture in the western United States, while applications to the 2023\u20132024 Amazon drought identify widespread soil moisture deficits accompanied by spatially heterogeneous vegetation responses. A further extension to a two-layer snow\u2013soil system demonstrates the potential for snow water equivalent (SWE) estimation using multi-frequency microwave observations, subject to prescribed snow properties and calibrated parameters.

This homogeneity imposes similar properties across the materials, limiting their ability to accommodate spatially varying material properties and functional demands and creating abrupt property mismatches at interfaces. Spatial gradient architectures, in which composition or geometry varies gradually and deliberately across a material, offer a strategy to distribute local properties according to these demands without introducing additional material components.\u003C\/p\u003E\u003Cp\u003EThis work investigates spatial gradients in composition and geometry as independent design variables through two systems. In a six-layer laminated cellulose nanocrystal (CNC)\/waterborne polyurethane (WPU) elastomer, the MXene content increases from 0 to 2 wt% at a fixed CNC\/WPU ratio. At the same average loading as a uniform film, the compositional gradient film shows approximately 50% higher tensile strength while maintaining a comparable strain at break, along with a further 15% reduction in heat capacity change in the soft-segment region and a higher storage modulus, consistent with spatially heterogeneous polymer confinement induced by the compositional gradient. In a liquid metal (LM)\/styrene-ethylene-butylene-styrene (SEBS) connector for ultrathin skin electrodes, the thickness increases from 0.5 to 10 \u03bcm over 5 cm. The connector follows skin topography, remains conductive to approximately 1100% strain and through 5,000 bending cycles, and gives an electrocardiography (ECG) signal-to-noise ratio of 20.1 dB during bending, compared with 13.7 dB for the corresponding commercial tape-based connector system. The thickness gradient is designed to combine the conformability of the thin region with the mechanical robustness of the thick region, providing a gradual transition that reduces mechanical mismatch across the device interface.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EThis work will provide a fundamental understanding of how spatial gradients in composition and geometry govern local material response and overall performance in soft elastomeric materials through studies of gradient architecture, local property distribution, and interfacial mechanics.

There is an ongoing need for novel lipids which are highly potent, safe, and minimize off-target delivery. First, I will walk through how we screened dozens of chemically distinct ionizable lipids (which are the heart of LNPs) to obtain a lipid class which meets all these criteria. Next, I will demonstrate extensive mouse validation showing that our lead LNP27 is 10x more potent than Moderna\u2019s vaccine LNP, while maintaining an excellent on\/off target ratio and safety profile. We finally demonstrate functional delivery of a reporter protein in non-human primates (NHPs) at a low dose. This pseudo-clinical trial approach minimizes loss of life by using NHPs that are already scheduled for euthanasia due to chronic illness. Having validated LNP27 thoroughly, I next aimed to examine how it can deliver a therapeutic cargo. CAR T therapy has revolutionized cancer treatment, saving the lives of many relapsed patients who otherwise had a bleak prognosis. However the current standard-of-care involves immense cost (~$0.5 million) and other challenges. LNPs have the potential to facilitate\u0026nbsp;in vivo\u0026nbsp;CAR therapy, bypassing many of these challenges and potentially making this lifesaving option more accessible. If in vivo\u0026nbsp;CAR continues to work, it has the potential to once again revolutionize not just CAR therapy, but cancer treatment at large. As one of many examples: Orna, a start-up company using ligand-free LNPs to generate in vivo CAR, was acquired for $2.4 billion this February. In parallel to these translationally-focused tracks, I also used one of these novel lipids to probe more fundamental questions of how LNP design affects stability and immunogenicity, curious how the design rules and dogmas established by\/for earlier generations of LNPs apply today. In summary, this thesis will expose the design and validation process of a novel class of LNPs, explore their potential for therapeutic application, and examine how they interplay with widely-held beliefs in the field.\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EA Novel Amino Lipid Series for mRNA Delivery, validated in pseudo-clinical trials\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"A Novel Amino Lipid Series for mRNA Delivery, validated in pseudo-clinical trials"}],"uid":"27707","created_gmt":"2026-10-19 17:31:09","changed_gmt":"2026-10-19 17:31:47","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-06T08:00:00-05:00","event_time_end":"2026-11-06T11:00:00-05:00","event_time_end_last":"2026-11-06T11:00:00-05:00","gmt_time_start":"2026-11-06 13:00:00","gmt_time_end":"2026-11-06 16:00:00","gmt_time_end_last":"2026-11-06 16:00:00","rrule":null,"timezone":"America\/New_York"},"location":"HSRB II, N600 ","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693297":{"#nid":"693297","#data":{"type":"event","title":"PhD Defense by Sebasti\u00e1n Guti\u00e9rrez Hern\u00e1ndez.","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003ETitle:\u003C\/strong\u003E \u2018Learning and optimizing paths between probability distributions.

A broad class of these problems can be formulated through an action functional defined over curves of probability distributions.

During brief bursts of activity called sharp-wave ripples, hippocampal neurons reactivate representations of past experiences, supporting memory consolidation. Microglia, the brain\u2019s resident immune cells, interact with neurons and influence network activity, yet whether they contribute to the hippocampal changes required for new spatial learning remains unknown. Establishing their role in healthy animals will provide a foundation for understanding memory impairment in Alzheimer\u2019s disease, where both microglial function and hippocampal activity are altered. This project will determine how microglia contribute to behavioral, network, and molecular changes during spatial learning in healthy adult mice. I hypothesize that microglia are engaged during learning and are necessary for the coordinated neuronal activity and gene-expression changes that support acquisition of new spatial information. Preliminary findings suggest increased expression of CD68, a marker associated with microglial activation and phagocytic activity, in hippocampal area CA3 after exposure to new reward locations. Behavioral findings also suggest that systemic microglial depletion may impair new spatial learning. To test this hypothesis, mice will first learn reward locations on a familiar virtual-reality track and then receive a microglia-depleting treatment directly into the hippocampus or a vehicle control. Recordings from hippocampal areas CA1 and CA3 during familiar-track performance and subsequent novel-track learning will assess spatial representations, sharp-wave ripple properties, and reactivation of newly learned spatial information. Bulk RNA sequencing of the hippocampus will identify learning-associated gene-expression changes and determine how depletion alters neuronal plasticity programs and responses in other brain cell populations. Vehicle-treated mice remaining on the familiar track will provide a comparison for identifying molecular responses associated with new learning. I predict that microglial depletion will preserve familiar-task performance but impair novel-track learning, reduce ripple-associated reactivation, and attenuate learning-associated neuronal plasticity programs. By connecting cellular responses with hippocampal activity and behavior, this work will test whether microglia actively support spatial learning and identify candidate pathways for future investigation of memory dysfunction in Alzheimer\u2019s disease\u003Cbr\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EMicroglial Regulation of Hippocampal Neural Activity During Spatial Learning\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Microglial Regulation of Hippocampal Neural Activity During Spatial Learning"}],"uid":"27707","created_gmt":"2026-10-19 15:46:02","changed_gmt":"2026-10-19 15:46:50","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-04T13:00:00-05:00","event_time_end":"2026-11-04T15:00:00-05:00","event_time_end_last":"2026-11-04T15:00:00-05:00","gmt_time_start":"2026-11-04 18:00:00","gmt_time_end":"2026-11-04 20:00:00","gmt_time_end_last":"2026-11-04 20:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Clough Undergraduate Learning Commons, room 127","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693294":{"#nid":"693294","#data":{"type":"event","title":"PhD Defense by Tomoki Koike","body":[{"value":"\u003Cp\u003EStudent Name: Tomoki Koike\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EAdvisor: Dr. Elizabeth Qian\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EMilestone: PhD Thesis Final Examination (Defense)\u003Cbr\u003E\u003Cbr\u003EDegree Program: Aerospace Engineering\u003Cbr\u003E\u003Cbr\u003ETitle: Data-Driven Nonlinear Reduced Model Learning with Stability Guarantee and Large-Scale Adaptation\u003Cbr\u003E\u003Cbr\u003EAbstract: High-fidelity numerical models of engineering systems have become increasingly accurate, but their computational and memory costs remain a barrier to many-query tasks such as design optimization, uncertainty quantification, and control. The field of scientific machine learning (SciML) aims to address these costs by combining data-driven learning with physical knowledge to construct accurate, efficient surrogate models. This thesis develops new SciML methods based on Operator Inference (OpInf), a method that learns low-dimensional surrogate models from trajectory data without access to the underlying simulation code by fitting the operators of a prescribed polynomial model through least-squares regression. Although this structure facilitates analysis, it does not guarantee that the learned model inherits the stability of the original system. Moreover, the batch formulation requires that all training data be loaded into memory, limiting its applicability to large-scale systems. This thesis addresses these two challenges: stability and scalability. For stability, we propose Energy-Preserving OpInf, which constrains the learned quadratic operator to conserve energy, yielding provably bounded reduced dynamics when the linear dynamics are dissipative. We further propose a complementary method called Lyapunov Function Inference, which uses trajectory data alone to approximate solutions of Zubov\u2019s equation, a nonlinear partial differential equation whose solution characterizes the stability region of an asymptotically stable equilibrium. By minimizing the equation\u2019s residual over polynomial candidates, the method constructs Lyapunov functions to certify stability and estimate this region. For scalability, we develop Streaming OpInf, a method that combines streaming singular value decomposition with recursive least-squares to learn reduced models from incoming data without storing the full dataset. An accompanying error analysis bounds errors in the learned operators in terms of the incrementally updated subspaces. Beyond benchmark problems, we demonstrate Streaming OpInf on three large-scale turbulent flows that present significant memory challenges for batch OpInf: a compressible magnetohydrodynamic flow, a turbulent channel flow, and an atmospheric boundary layer flow with nearly 24 million states. We achieve models that reproduce relevant flow statistics while reducing memory requirements by 60\u201390%. Together, these contributions advance SciML for applications requiring stable learned dynamics and memory-efficient model construction.\u003Cbr\u003E\u003Cbr\u003EDate and time: 2026-11-12, 2:30 pm to 4:30 pm\u003Cbr\u003E\u003Cbr\u003ELocation: MK317\u003Cbr\u003E\u003Cbr\u003ECommittee:\u003Cbr\u003EDr. Elizabeth Qian (advisor), School of Aerospace Engineering\u003Cbr\u003EDr. Keegan Moore, School of Aerospace Engineering\u003Cbr\u003EDr. Joseph Oefelein, School of Aerospace Engineering\u003Cbr\u003EDr. Benjamin Peherstorfer, \u00c9cole Polytechnique F\u00e9d\u00e9rale de Lausanne\u003Cbr\u003EDr. Christopher G.

This dissertation develops mathematical models and solution methods for resilient constellation design and management by combining operations research with orbital mechanics. The goal is to support early-stage architecture decisions through the evaluation of cost, service performance, and operational feasibility. The first part addresses regional constellation design that incorporates in-plane spares for failure recovery and accounts for launch costs. Candidate orbital slots are constructed using a Walker-Delta arrangement, and the design problem is formulated as a mixed-integer linear program (MILP). For large candidate sets, the greedy randomized adaptive search procedure (GRASP) identifies promising orbital planes, and a reduced MILP determines the final constellation. The second part addresses spare replenishment for large-scale constellations. It compares launches to individual orbital planes with replenishment architectures that use J2-driven nodal precession to reduce launch costs. Markov chain models combined with inventory control enable rapid analysis of stochastic failures, spare availability, and replenishment delays. The resulting cost and service-performance measures support the optimization of replenishment policies and architectures under specified performance requirements. The third part addresses on-orbit servicing for expensive satellites with repairable failures. Uncertain failures are represented through service-demand rates, and queueing models determine the required servicing capacity. A J2-aware transfer model captures the trade-off between maneuver cost and service duration. These models are incorporated into a MILP to determine depot locations, servicer numbers, and demand allocation. Time aggregation and a revised rolling-horizon method reduce the computational scale. Planned work will address servicing and fuel-replenishment decisions through queue-based dispatch.\u003Cbr\u003E\u003Cbr\u003EDate and time: 2026-10-29, 9:30 AM - 11:30 AM\u003Cbr\u003E\u003Cbr\u003ELocation: Coda C1015 Vinings\u003Cbr\u003E\u003Cbr\u003ECommittee:\u003Cbr\u003EDr. Koki Ho (advisor), School of Aerospace Engineering\u003Cbr\u003EDr. Brian C.

Embedded rNMPs are the most abundant naturally occurring noncanonical nucleotides in genomic DNA. Although several pathways process or remove embedded rNMPs, their genomic distribution, biological consequences, and mechanisms of removal remain incompletely understood.\u003C\/p\u003E\u003Cp\u003EIn this study, we developed rNMPID, a publicly accessible database that integrates rNMP-mapping datasets across species, genotypes, and sequencing techniques. rNMPID enables standardized analyses of rNMP composition, sequence context, strand bias, and enrichment across genomic features, providing a valuable resource for comparing rNMP landscapes across studies.\u003C\/p\u003E\u003Cp\u003ESecond, we characterized the distribution of embedded rNMPs in human mitochondrial DNA across multiple cell types using ribose-seq. We found that rNMP distribution was non-random, with preferential enrichment on the light strand in most cell types, recurrent rNMP hotspots, and distinct patterns associated with mitochondrial DNA replication and transcription.\u003C\/p\u003E\u003Cp\u003E\u003Cbr\u003EFinally, we investigated how RNase H1, RNase H2, and topoisomerase I (Top1) shape the genome-wide distribution of embedded rNMPs in budding yeast nuclear DNA. We found that RNase H2 and Top1 influence rNMP accumulation on the leading strand of DNA replication, whereas RNase H1 deficiency preferentially affects lagging-strand associated rNMP accumulation. We further identified pervasive transcription-associated rNMP strand asymmetry, characterized by preferential enrichment on the non-template strand of transcribed genes. This asymmetry was particularly pronounced at highly transcribed loci, including ribosomal RNA genes. Moreover, rNMP-enriched regions overlapped R-loop enriched regions, and RNase H1 overexpression attenuated non-template strand bias, supporting a connection between R-loop metabolism and the distribution of embedded rNMPs.\u003C\/p\u003E\u003Cp\u003E\u003Cbr\u003EOverall, this work demonstrates that the genomic distribution of embedded rNMPs is non-random and reflects the combined influences of DNA replication, transcription, and rNMP-processing pathways. These findings, together with the development of rNMPID, provide a foundation for investigating the roles of embedded rNMPs in genome stability and human diseases associated with defective nucleic acid metabolism, including Aicardi-Gouti\u00e8res syndrome.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cstrong\u003EWhen DNA meets RNA: Ribonucleotides Embedded in the Genome\u003C\/strong\u003E\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"When DNA meets RNA: Ribonucleotides Embedded in the Genome"}],"uid":"27707","created_gmt":"2026-10-19 15:37:45","changed_gmt":"2026-10-19 15:38:16","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-10-29T13:00:00-04:00","event_time_end":"2026-10-29T14:00:00-04:00","event_time_end_last":"2026-10-29T14:00:00-04:00","gmt_time_start":"2026-10-29 17:00:00","gmt_time_end":"2026-10-29 18:00:00","gmt_time_end_last":"2026-10-29 18:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Engineered Biosystems Building (EBB), CHOA seminar room EBB 1005","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693289":{"#nid":"693289","#data":{"type":"event","title":"PhD Proposal by Sam (Sheng-You) Chen","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003ESam (Sheng-You) Chen\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBioE PhD Proposal Presentation\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EWednesday, November 4th, 2026, at 10:00 am\u003C\/p\u003E\u003Cp\u003ELocation: IBB Suddath Seminar Room (1128)\u003C\/p\u003E\u003Cp\u003EZoom Link:\u0026nbsp;\u003Ca href=\u0022https:\/\/nam12.safelinks.protection.outlook.com\/?url=https%3A%2F%2Fgatech.zoom.us%2Fj%2F4256237492%3Fomn%3D96368139923\u0026amp;data=05%7C02%7Cannouncements%40grad.gatech.edu%7C930e34af56ef4aa5da7208df2ba3952a%7C482198bbae7b4b258b7a6d7f32faa083%7C1%7C0%7C639277653752008502%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C\u0026amp;sdata=ZReqUAR2PXXI%2BfO7pTTGIgOxc5sDAe17rLAMp6vc%2Fdo%3D\u0026amp;reserved=0\u0022 target=\u0022_blank\u0022\u003Ehttps:\/\/gatech.zoom.us\/j\/4256237492?omn=96368139923\u003C\/a\u003E\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EAdvisor:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EDr. Todd Sulchek, George W.

Unlike conventional therapeutics, living cells are sensitive to mechanical forces encountered during manufacturing, from deformation during fluid processing to interactions with engineered materials during expansion. This research aims to advance the understanding of cell mechanical responses and develop microsystems that harness and control mechanical interactions during cell therapy manufacturing. In Aim 1, I will investigate how deformation rate and strain influence cell relaxation and damage responses, advancing fundamental understandings that inform the design of cell-processing systems. In Aim 2, I will develop a microfluidic workflow to label non-phagocytic cells with perfluorocarbon ultrasound contrast agents to enable non-invasive, real-time \u003Cem\u003Ein vivo\u003C\/em\u003E tracking at single cell level. A system of microfluidic devices will be used. First a microfluidic mixer will be used to spontaneous emulsification to form nanodroplets. Second, the resulting nanodroplets will then be directed to a microfluidic mechanoporation chip for delivery into T-cells. In Aim 3, I will develop more cell-like antigen-presenting particles with controlled size and stiffness using a feedback-controlled microfluidic platform to produce hydrogel particles. The feedback-control platform uses real-time independent assessments of particle size and stiffness to modify the flow of input materials to achieve a dramatic reduction in property drift. As a result, synthetic antigen-presenting hydrogel particles with cell-like properties will be created and used to investigate how mechanical properties can be tuned to enhance T-cell expansion and promote desirable memory and stem-like phenotypes. Together, these studies will bridge fundamental cell mechanics and engineering applications, laying the foundation for more controlled and reliable cell therapy manufacturing.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EMechanics-Driven Microsystems for Cell Therapy Manufacturing\u003C\/strong\u003E\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":" Mechanics-Driven Microsystems for Cell Therapy Manufacturing"}],"uid":"27707","created_gmt":"2026-10-19 15:29:33","changed_gmt":"2026-10-19 15:30:17","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-04T10:00:00-05:00","event_time_end":"2026-11-04T12:00:00-05:00","event_time_end_last":"2026-11-04T12:00:00-05:00","gmt_time_start":"2026-11-04 15:00:00","gmt_time_end":"2026-11-04 17:00:00","gmt_time_end_last":"2026-11-04 17:00:00","rrule":null,"timezone":"America\/New_York"},"location":"IBB Suddath Seminar Room (1128)","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}},"693260":{"#nid":"693260","#data":{"type":"event","title":"Ph.D. Dissertation Defense - Hanqiu Chen","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003ETitle\u003C\/strong\u003E\u003Cem\u003E:\u0026nbsp; Architecture, System and Tool Co-Design For Memory and Storage Efficient Machine Learning\u003C\/em\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECommittee:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EDr.\u0026nbsp;Callie Hao, ECE, Chair, Advisor\u003C\/p\u003E\u003Cp\u003EDr.\u0026nbsp;Divya Mahajan, ECE\u003C\/p\u003E\u003Cp\u003EDr.\u0026nbsp;Celine Lin, CS\u003C\/p\u003E\u003Cp\u003EDr.\u0026nbsp;Shuyi Pei, Samsung\u003C\/p\u003E\u003Cp\u003EDr.\u0026nbsp;Yiran Chen, Duke\u003C\/p\u003E\u003Cp\u003EDr. Yuan Xie, Hong Kong UST\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EModern machine learning workloads place growing demands on memory capacity, storage space, and data communication.

These moons are constantly exposed to the (sub)corotating plasma occupying the Jovian magnetosphere as it overtakes their orbital motion. Jupiter\u0027s dipolar and spin axes are offset by 9.6\u00ba so the ambient plasma properties and magnetic fields at the moons oscillate with the Jovian synodic period (\u224811 hr). The time-variable magnetic field drives an observable inductive response in the putative saline subsurface ocean inside each moon. Ganymede also boasts a permanent, dynamo-driven dipole field that locally dominates Jupiter\u0027s field, constructing a mini-magnetosphere. These objects\u0027 tenuous atmospheres and internal fields interact with Jupiter\u0027s magnetosphere, generating perturbations in the electromagnetic fields and plasma flow. Atmospheric inhomogeneities and induction signatures affect the morphology of these perturbations, providing a glimpse into moon properties. However, three-dimensional characterization of the moon-plasma interaction regions requires information assembled from many spacecraft flybys under similar ambient conditions. Fortunately, there exists another avenue to characterize plasma interactions using the energetic ion population of Jupiter\u0027s magnetosphere. Charge exchange between such ions and atmospheric neutrals generates energetic neutral atoms (ENAs), which travel away along straight lines due to their high inertia. The Jupiter Icy Moons Explorer (JUICE) mission will arrive at Jupiter in 2031 and capture ENA images of the icy Galilean satellites using a detector analogous to a camera for ENAs. Since the energetic ions are guided into the moons\u0027 atmospheres by the locally deformed electromagnetic fields, ENA emissions are encoded with information on the structure of the fields as well as the atmospheres and ambient energetic ion populations. Hence, ENA images are two-dimensional \u201csnapshots\u201d of a moon\u0027s interaction region that complement magnetometer and plasma data collected in situ. However, this information is intertwined within the images in a complex way. Therefore, we develop a theoretical framework to facilitate the planning and analysis of upcoming ENA observations by JUICE. We present a suite of models that determines the ENA emissions for a given set of ambient magnetospheric parameters and configurations of each moon\u0027s atmosphere. First, we calculate global maps of the ENA flux through a sphere encapsulating the atmosphere. Next, we emulate the detector aboard JUICE to produce synthetic ENA images for a variety of vantages. We demonstrate that ENA emissions at Europa and Callisto are observable in a band oriented perpendicular to the ambient field direction, while the closed dipolar field lines at Ganymede reduce the ENA emissions emanating from this moon\u0027s equatorial regions. Analysis of hundreds of synthetic ENA images indicates that, for certain detector vantages, each moon\u0027s plasma interaction leaves unique signatures in the emissions. \u0026nbsp;\u0026nbsp;\u003Cbr\u003ECommittee\u003Cbr\u003E\u2022\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;Prof. \u0026nbsp;Sven Simon \u2013 School of Earth and Atmospheric Sciences and School of Physics (advisor) \u0026nbsp;\u003Cbr\u003E\u2022\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;Dr. Lucas Liuzzo \u2013 Space Sciences Laboratory, University of California, Berkeley\u003Cbr\u003E\u2022\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;Prof. Samer Naif \u2013 School of Earth and Atmospheric Sciences \u0026nbsp;\u003Cbr\u003E\u2022\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;Prof. A.

Study 1 uses transcranial magnetic stimulation (TMS) to\u0026nbsp;establish\u0026nbsp;when confidence is computed, revealing that the dorsolateral prefrontal cortex (DLPFC) contributes to confidence during a broad temporal window overlapping with decision-making. Study 2 tests competing computational theories\u0026nbsp;\u2014\u0026nbsp;Bayesian Confidence Hypothesis (BCH) versus Confidence in Raw Evidence Space (CRES)\u0026nbsp;\u2014\u0026nbsp;in two-choice tasks, finding consistent support for evidence-based rather than probability-based confidence computation. Study 3 extends this investigation to multi-alternative decisions using a novel dot numerosity paradigm,\u0026nbsp;demonstrating\u0026nbsp;that confidence tracks the difference between the two highest evidence values rather than choice probability. Together, these studies advance a mechanistic framework in which confidence\u0026nbsp;emerges\u0026nbsp;in parallel with decisions and\u0026nbsp;operates\u0026nbsp;on sensory evidence rather than probability estimates.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EThe Computation of Confidence in Perceptual Decision-Making\u0026nbsp;\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"The Computation of Confidence in Perceptual Decision-Making "}],"uid":"27707","created_gmt":"2026-09-08 15:26:09","changed_gmt":"2026-09-08 15:26:48","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-11-10T10:00:00-05:00","event_time_end":"2026-11-10T23:00:00-05:00","event_time_end_last":"2026-11-10T23:00:00-05:00","gmt_time_start":"2026-11-10 15:00:00","gmt_time_end":"2026-11-11 04:00:00","gmt_time_end_last":"2026-11-11 04:00:00","rrule":null,"timezone":"America\/New_York"},"location":"ZOOM","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
