Amino acids, the building blocks of proteins, are among the most promising biosignature targets due to their universal role in life as we know it, their stability over geologic timescales, and their detectability with existing instrumentation. However, amino acids also form through abiotic chemistry throughout the solar system, and existing methods for distinguishing biotic from abiotic origins are limited by overlapping signatures between the two, or by degradation of the biotic signature under environmental conditions. This dissertation explores the HOMO-LUMO gap, a chemical property reflecting molecular electron reactivity, as a biosignature capable of overcoming these limitations. Three lines of work support this investigation: (i) demonstrating that this property can be measured directly using single-molecule nanogap instrumentation, including a flight-validated prototype tested under space-analog conditions; (ii) characterizing how pH, temperature, and solvent polarity influence this property across a broad set of amino acids, and evaluating its stability under the geochemical conditions predicted for Enceladus, Europa, and Mars; and (iii) constructing a quantitative framework that applies this property to distinguish biotic from abiotic amino acid samples with high accuracy. Taken together, this dissertation establishes a biosignature framework grounded in the fundamental electronic chemistry of life. It further finds that the electronic landscape of amino acids reflects the biochemical stages proposed for early genetic code diversification, consistent with environmental selection shaping life\u0027s amino acid repertoire, and offering an insight into the chemical logic underlying life as we know it. The developed framework is also measurable with flight-ready instrumentation, and applicable to current and future missions in the search for life across the solar system.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EThe HOMO-LUMO Gap of Amino Acids as a Marker of Genetic Code Selection and a Biosignature for Life Detection\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":" The HOMO-LUMO Gap of Amino Acids as a Marker of Genetic Code Selection and a Biosignature for Life Detection"}],"uid":"27707","created_gmt":"2026-06-24 16:16:35","changed_gmt":"2026-06-24 16:17:01","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-07-08T13:00:00-04:00","event_time_end":"2026-07-08T15:00:00-04:00","event_time_end_last":"2026-07-08T15:00:00-04:00","gmt_time_start":"2026-07-08 17:00:00","gmt_time_end":"2026-07-08 19:00:00","gmt_time_end_last":"2026-07-08 19:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Ford ES\u0026T L1255","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":""}},"690896":{"#nid":"690896","#data":{"type":"event","title":"PhD Defense by Jiangpeiyun Jin","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003EMs. Jiangpeiyun Jin\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EThesis\u0026nbsp;Title: \u0022Metabolomic Analysis of Antibiotic-Mediated Secondary Metabolism and Interkingdom Interactions in \u003C\/strong\u003E\u003Cem\u003E\u003Cstrong\u003EBurkholderia cenocepacia\u003C\/strong\u003E\u003C\/em\u003E\u003Cstrong\u003E\u0022\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EDate and time:\u003C\/strong\u003E Wednesday, July 1st, 2026 at 9:00 AM\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ELocation:\u003C\/strong\u003E Krone Engineered Biosystems Building (EBB) -

This research develops a physics-informed monocular visual simultaneous localization and mapping (SLAM) framework that embeds the coupled orbital and rigid-body equations of motion as factor-graph constraints, so that a single passive camera, aided by an attitude reference, recovers both the inspector\u2019s relative trajectory and the target\u2019s angular velocity, inertia tensor, and center of mass (COM) location. The objective is to characterize and extend the observability of these quantities across the full inspection regime, from well-resolved close range to partially resolved long range where the target subtends only a few tens of pixels, for passively tumbling, non-cooperative targets. The methodology combines analytic and empirical observability studies, ablations on photo-realistically rendered inspection sequences, and a trust-gated dynamics propagator that quantifies when a dynamics-based estimate is safe to consume. The work culminates in a decentralized cooperative formulation in which multiple inspectors share dynamics-consistent estimates, transfer custody across observation gaps, and establish a common target frame across viewpoints. The significance is a model-free, infrastructure-independent navigation capability for the unstructured proximity operations that future servicing, active debris removal, and space-domain-awareness missions require.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EToward Autonomous Relative Navigation and Characterization of Unknown Resident Space Objects\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Toward Autonomous Relative Navigation and Characterization of Unknown Resident Space Objects"}],"uid":"27707","created_gmt":"2026-06-24 12:40:14","changed_gmt":"2026-06-24 12:40:45","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-06-25T10:30:03-04:00","event_time_end":"2026-06-25T12:30:00-04:00","event_time_end_last":"2026-06-25T12:30:00-04:00","gmt_time_start":"2026-06-25 14:30:03","gmt_time_end":"2026-06-25 16:30:00","gmt_time_end_last":"2026-06-25 16:30:00","rrule":null,"timezone":"America\/New_York"},"location":"Montgomery Knight Rm 317 or via Teams ","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":""}},"690881":{"#nid":"690881","#data":{"type":"event","title":"PhD Defense by Logan Brabson","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003EPhD Thesis\u0026nbsp;Defense Announcement\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EStudent Name: Logan Brabson\u003C\/p\u003E\u003Cp\u003EThesis Title: Datasets, models, and concepts to advance computational discovery of metal-organic frameworks for direct air capture\u003C\/p\u003E\u003Cp\u003EThesis Advisor: AJ Medford\u003C\/p\u003E\u003Cp\u003EThesis Co-Advisor: David Sholl\u003C\/p\u003E\u003Cp\u003ECommittee Members: Matthew Realff (CHBE), Chris Jones (CHBE), Jesse McDaniel (Chemistry)\u003C\/p\u003E\u003Cp\u003EDate: 07\/09\/2026\u003C\/p\u003E\u003Cp\u003ETime: 10 AM EDT\u003C\/p\u003E\u003Cp\u003ELocation: Ford ES\u0026amp;T L1205\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EDatasets, models, and concepts to advance computational discovery of metal-organic frameworks for direct air capture\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Datasets, models, and concepts to advance computational discovery of metal-organic frameworks for direct air capture"}],"uid":"27707","created_gmt":"2026-06-24 12:38:15","changed_gmt":"2026-06-24 12:38:48","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-07-09T10:00:00-04:00","event_time_end":"2026-07-09T12:00:00-04:00","event_time_end_last":"2026-07-09T12:00:00-04:00","gmt_time_start":"2026-07-09 14:00:00","gmt_time_end":"2026-07-09 16:00:00","gmt_time_end_last":"2026-07-09 16:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Ford ES\u0026T L1205","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":""}},"690880":{"#nid":"690880","#data":{"type":"event","title":"Ph.D. Dissertation Defense -

The functionalities hoped to be achieved by this research work are link assessment with adaptive modulation, detection and identification of tags with harmonic signature generation, and simultaneous communications with multiple tags. RFID tags use minimalist and low-power (micro-watts) circuitry. Their simple hardware design has made RFID technology and its backscatter communication techniques prime candidates to be the foundation of future energy-efficient wireless communications systems. New features, such as adaptive modulation, harmonic signature identification, and simultaneous communications, will make RFID technology more robust and versatile so that it can be used in any environment for any applications in ever-growing cyber-physical radio systems.\u003C\/div\u003E\u003C\/div\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Next-Generation RFID with Adaptive Modulation, Harmonic Identification, and Simultaneous Communications"}],"uid":"36804","created_gmt":"2026-06-23 19:25:08","changed_gmt":"2026-06-23 19:31:19","author":"jjones779","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-07-07T12:30:00-04:00","event_time_end":"2026-07-07T14:30:00-04:00","event_time_end_last":"2026-07-07T14:30:00-04:00","gmt_time_start":"2026-07-07 16:30:00","gmt_time_end":"2026-07-07 18:30:00","gmt_time_end_last":"2026-07-07 18:30:00","rrule":null,"timezone":"America\/New_York"},"location":"Room 4222, Price Gilbert ","extras":[],"related_links":[{"url":"https:\/\/gatech.zoom.us\/j\/92762097823?pwd=hrny68PJwhOksJfUathEbOpevTuGtt.1","title":"Zoom Link"}],"groups":[{"id":"434381","name":"ECE Ph.D. Dissertation Defenses"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"},{"id":"1808","name":"graduate students"}],"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":""}},"690874":{"#nid":"690874","#data":{"type":"event","title":"PhD Defense by Youngsu Shin","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003EPhD Thesis\u0026nbsp;Defense Announcement\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EStudent Name: Youngsu Shin\u003C\/p\u003E\u003Cp\u003EThesis Title: RADIATION-TRIGGERED DEPOLYMERIZATION OF POLY(ALDEHYDE) FOR PHASE CHANGE, PAYLOAD RELEASE, AND DRY-DEVELOP LITHOGRAPHY\u003C\/p\u003E\u003Cp\u003EThesis Advisor: Paul Kohl\u003C\/p\u003E\u003Cp\u003EThesis Co-Advisor: N\/A\u003C\/p\u003E\u003Cp\u003ECommittee Members: Dr. Satish Kumar, School of Materials Science and Engineering; Dr. Will Gutekunst, School of Materials Science and Engineering; Dr. Fani Boukouvala, School of Chemical and Biomolecular Engineering; Dr. Julia Yang, School of Chemical and Biomolecular Engineering\u003C\/p\u003E\u003Cp\u003EDate: 06\/26\/2026\u003C\/p\u003E\u003Cp\u003ETime: 10 am\u003C\/p\u003E\u003Cp\u003ELocation: Bunger-Henry 388\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003ERADIATION-TRIGGERED DEPOLYMERIZATION OF POLY(ALDEHYDE) FOR PHASE CHANGE, PAYLOAD RELEASE, AND DRY-DEVELOP LITHOGRAPHY\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"RADIATION-TRIGGERED DEPOLYMERIZATION OF POLY(ALDEHYDE) FOR PHASE CHANGE, PAYLOAD RELEASE, AND DRY-DEVELOP LITHOGRAPHY"}],"uid":"27707","created_gmt":"2026-06-23 16:20:36","changed_gmt":"2026-06-23 16:21:10","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-06-26T10:00:00-04:00","event_time_end":"2026-06-26T12:00:00-04:00","event_time_end_last":"2026-06-26T12:00:00-04:00","gmt_time_start":"2026-06-26 14:00:00","gmt_time_end":"2026-06-26 16:00:00","gmt_time_end_last":"2026-06-26 16:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Bunger-Henry 388","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":""}},"690873":{"#nid":"690873","#data":{"type":"event","title":"PhD Defense by Sucharita Vijayaraghavan","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003EPhD Thesis\u0026nbsp;Defense Announcement\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EStudent Name: Sucharita Vijayaraghavan\u003C\/p\u003E\u003Cp\u003EThesis Title: Tuning Active Site Structure and Reactivity of Pd-based Catalysts for Thermochemical Oxygen Reduction Reactions\u003C\/p\u003E\u003Cp\u003EThesis Advisor: David W.

Compared to other additive methods that deposit material at grams-per-hour, wire-arc can deposit material at kilograms-per-hour. The addition of a robot manipulator allows for the development of more complex and much larger geometries than traditional machining platforms. When depositing large amounts of material, many variables become more critical to the process effecting final product quality. Many of these variables, such as heat input, are directly controlled by the thermal properties fo the material selected. While trajectories for robotic additive manufacturing have been studied, the design of optimal trajectories that prioritize local thermomechanical conditions are not as well understood. This dissertation aims to address this gap through: (1) exploration of the efficacy of intersecting path-plan strategies for the infill of wire-arc parts, (2) investigating the impact of various intersecting path-plan strategies on thermomechanical response and part quality, and (3) studying how these strategies might be implemented for closed-loop online control algorithms. This work is impactful in providing new tools and methods for manufacturing process developers to optimize trajectories that enable deposition during the cooling process, while reducing thermal gradients and improving geometric accuracy and surface finish. Most importantly, it reduces the time needed to print large-scale components over current robotic additive methods. \u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003ETrajectory Optimization Based on Thermal Data in a Robotic Wire-Arc Additive Manufacturing System\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Trajectory Optimization Based on Thermal Data in a Robotic Wire-Arc Additive Manufacturing System"}],"uid":"27707","created_gmt":"2026-06-22 17:33:40","changed_gmt":"2026-06-22 17:34:10","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-07-14T12:00:00-04:00","event_time_end":"2026-07-14T14:00:55-04:00","event_time_end_last":"2026-07-14T14:00:55-04:00","gmt_time_start":"2026-07-14 16:00:00","gmt_time_end":"2026-07-14 18:00:55","gmt_time_end_last":"2026-07-14 18:00:55","rrule":null,"timezone":"America\/New_York"},"location":" GTMI 114 or via 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":""}},"690844":{"#nid":"690844","#data":{"type":"event","title":"PhD Defense by Benjamin Cobb","body":[{"value":"\u003Cp\u003ETitle: Novel Tensor Factorization Algorithms and Applications\u003C\/p\u003E\u003Cp\u003EDate: Thursday, July 2nd (7\/2), 2026\u003C\/p\u003E\u003Cp\u003ETime: 12:00-2:00pm ET\u003C\/p\u003E\u003Cp\u003ELocation: Coda C1315 (Grant Park)\u003C\/p\u003E\u003Cp\u003EZoom:\u0026nbsp;\u003Ca href=\u0022https:\/\/gatech.zoom.us\/j\/95337401341?pwd=UA3HGBasOpWtv4JIanQFoBKtyovP9y.1\u0022\u003Ehttps:\/\/gatech.zoom.us\/j\/95337401341?pwd=UA3HGBasOpWtv4JIanQFoBKtyovP9y.1\u003C\/a\u003E\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EBenjamin Cobb\u003C\/p\u003E\u003Cp\u003EComputer Science Ph.D. Candidate\u003C\/p\u003E\u003Cp\u003ESchool of Computational Science and Engineering\u003C\/p\u003E\u003Cp\u003EGeorgia Institute of Technology\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022https:\/\/www.ben-cobb.com\/\u0022\u003Ehttps:\/\/www.ben-cobb.com\/\u003C\/a\u003E\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003ECommittee:\u003C\/p\u003E\u003Cp\u003EDr. Richard W.

The process of computing low-rank tensor factorizations is computationally expensive and requires efficiently leveraging computational resources to enable feasibility. This\u0026nbsp;thesis\u0026nbsp;proposes several novel algorithms for low-rank tensor factorizations to enable interpretable analysis and compression of massive multiway datasets. To this end, we focus on three overarching themes: efficiently leveraging computational resources to compute large-scale tensor decompositions, efficiently enforcing nonnegativity constraints to improve interpretability, and incorporating additional information into the factorization to improve solution quality.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EWe start by proposing the Fused In-place Sequentially Truncated Higher Order Singular Value Decomposition (FIST-HOSVD) algorithm as the first in-place method for computing the dense Tucker decomposition, increasing the problem size that can be factorized by up to 3x. We demonstrate the effectiveness of the proposed FIST-HOSVD algorithm by decreasing the auxiliary memory consumption by over 135x when computing the dense Tucker decomposition on two combustion simulation compression applications. We then provide an in-depth study of several state-of-the-art methods for Nonnegative Matrix Factorization (NMF). As part of this, we provide a comprehensive survey of Nonnegative Least Squares (NNLS) solvers used to enforce the nonnegativity of the factors. In doing so, we propose a Fast Active-Set Thresholding NNLS (FAST-NNLS) solver which outperforms existing NNLS methods for broad classes of problems. We then introduce a GPU-accelerated Hierarchical NMF K-Means initialization method for large-scale protein clustering on commodity-grade hardware. We then propose the Low Rank Approximations with Constraints at Exascale (LORACX) framework for computing large-scale distributed NMF. We demonstrate that LORACX yields unprecedented performance and scalability by achieving 0.67 exaflops in double-precision on 8,192 nodes of the Frontier supercomputer when computing NMF of a 2.1 petabyte matrix. We then extend the NMF objective function to incorporate additional multiway data, culminating in a Joint Nonnegative Coupled Matrix-Tensor Factorization (Joint-NCMTF) framework. We demonstrate that the proposed Joint-NCMTF method yields improved clustering quality and additional dimensions of insight relative to traditional matrix-based methods.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003ENovel Tensor Factorization Algorithms and Applications\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Novel Tensor Factorization Algorithms and Applications"}],"uid":"27707","created_gmt":"2026-06-22 13:58:16","changed_gmt":"2026-06-22 13:58:52","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-07-02T12:00:00-04:00","event_time_end":"2026-07-02T14:00:00-04:00","event_time_end_last":"2026-07-02T14:00:00-04:00","gmt_time_start":"2026-07-02 16:00:00","gmt_time_end":"2026-07-02 18:00:00","gmt_time_end_last":"2026-07-02 18:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Coda C1315 (Grant Park)","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":""}},"690828":{"#nid":"690828","#data":{"type":"event","title":"Ph.D. Dissertation Defense - Richard Asiamah","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003ETitle\u003C\/strong\u003E\u003Cem\u003E:\u0026nbsp; Development and Applications of Synthetic Electric Grid Models for Underrepresented Regions\u003C\/em\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECommittee:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EDr. Daniel Molzahn, ECE, Chair, Advisor\u003C\/p\u003E\u003Cp\u003EDr. Saman Zonouz, ECE\u003C\/p\u003E\u003Cp\u003EDr. Constance Crozier, ISyE\u003C\/p\u003E\u003Cp\u003EDr. Jean-Paul Watson, Lawrence Livermore Nat Lab\u003C\/p\u003E\u003Cp\u003EDr. Santiago Grijalva, ECE\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EThe objective of the research is to develop algorithms and methods for creating synthetic electricity networks for regions with limited access to detailed power system data, particularly in parts of Africa, South America, and Asia.

By augmenting the capabilities of the ASHES software, the framework executes the placement and routing for each individual island before finalizing the routing across the entire system. Furthermore, this tool operates in tandem with ASHES to facilitate the synthesis of reconfigurable analog and mixed- signal layouts using programmable standard cell components. Once manufactured, the resulting hardware can be programmed via the ASHES environment, which incorporate the Versatile Place and Route (VPR) open-source tool. \u0026nbsp; A foundational element of this synthesis approach relies on crucial recent advancements in programmable standard cells that employ Floating-Gate (FG) devices to achieve high-precision parameter control. These FG-based innovations are pivotal, as they allow for elevated levels of abstraction in analog computation and make large-scale analog synthesis feasible. While this methodology is comprehensively demonstrated through the synthesis and tapeout of configurable chips utilizing a 350nm standard cell library, the underlying techniques are highly adaptable and can be generalized to other technology nodes, such as 130nm, 65nm, and 16nm.\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Empowering Analog Design with an Automated Tool Flow for Analog Synthesis and Programming "}],"uid":"28475","created_gmt":"2026-06-19 15:52:42","changed_gmt":"2026-06-19 15:52:56","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-06-26T14:00:00-04:00","event_time_end":"2026-06-26T16:00:00-04:00","event_time_end_last":"2026-06-26T16:00:00-04:00","gmt_time_start":"2026-06-26 18:00:00","gmt_time_end":"2026-06-26 20:00:00","gmt_time_end_last":"2026-06-26 20:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Room 523A, TSRB","extras":[],"groups":[{"id":"434381","name":"ECE Ph.D. Dissertation Defenses"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"},{"id":"1808","name":"graduate students"}],"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":""}},"690822":{"#nid":"690822","#data":{"type":"event","title":"Phd Defense by Cem Okan Yaldiz","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003ETitle\u003C\/strong\u003E: Multi-modal Temporal Physiological Modeling Across Varying Time Horizons Using Dynamical Interactions\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EDate\u003C\/strong\u003E: Monday, July 6, 2026\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ETime\u003C\/strong\u003E: 11:00 AM - 1:00 PM ET\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ELocation\u003C\/strong\u003E: TSRB523A + Remote\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ERemote Meeting Link:\u003C\/strong\u003E\u0026nbsp;\u003Ca href=\u0022https:\/\/gatech.zoom.us\/j\/99856255882?pwd=hgnvB6OKoETUl5k8DZGsXbioS7k43o.1\u0022\u003Ehttps:\/\/gatech.zoom.us\/j\/99856255882?pwd=hgnvB6OKoETUl5k8DZGsXbioS7k43o.1\u003C\/a\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ERemote Meeting ID\u003C\/strong\u003E: 998 5625 5882\u0026nbsp;| Passcode: 318520\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECem Okan Yaldiz\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003ERobotics Ph.D. Candidate\u003C\/p\u003E\u003Cp\u003ESchool of Electrical and Computer Engineering\u003C\/p\u003E\u003Cp\u003EGeorgia Institute of Technology\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECommittee\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EDr. Omer Inan (Advisor) - School of Electrical and Computer Engineering, Georgia Institute of Technology\u003C\/p\u003E\u003Cp\u003EDr. Thomas Ploetz\u0026nbsp;- School of Interactive Computing, Georgia Institute of Technology\u003C\/p\u003E\u003Cp\u003EDr. Vince Calhoun\u0026nbsp;- School of Electrical and Computer Engineering, Georgia Institute of Technology\u003C\/p\u003E\u003Cp\u003EDr. Reza Sameni - Wallace H.

At its core, the work emphasizes rigorous temporal modeling to capture the evolving dynamics of physiological states, enabling the design of predictive systems. The first contribution focuses on the early prediction of exertional heat stroke, a problem that inherently requires long-horizon inference to capture degradation in physiological state. By integrating deep learning with anomaly detection, the results show that multi-modal fusion achieves strong predictive performance, allowing the models to more faithfully represent the progression of physiological strain and stress. The dissertation then shifts to a short-horizon forecasting setting, targeting the precise timing of impending cardiac events such as aortic opening and closing. In this context, incorporating multi-modal inputs into a Kalman filter-based autoregressive framework is shown to significantly enhance accuracy, robustness, and computational efficiency. The work then examines the structural relationships among cardiac signals without target-based supervision to characterize a shared latent representation. By scaling the training data and primarily exploiting short windows of cardiac signals, the study demonstrates the effectiveness of structural self-supervised learning, particularly for distinguishing blood volume status levels. Finally, the scope is extended to cross-modal analysis of neural and cardiac signals, where multi-modal interactions are leveraged to enable the classification of major depressive disorder and preconscious responses. Taken together, this dissertation establishes that combining multi-modal fusion with principled temporal learning is key to modeling the complexity of physiological systems. Centered on cardiac data, the proposed approaches offer adaptable methodological frameworks, yielding both deeper physiological insight and robust, practical modeling strategies.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EMulti-modal Temporal Physiological Modeling Across Varying Time Horizons Using Dynamical Interactions\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Multi-modal Temporal Physiological Modeling Across Varying Time Horizons Using Dynamical Interactions"}],"uid":"27707","created_gmt":"2026-06-18 18:39:43","changed_gmt":"2026-06-18 18:40:17","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-07-06T11:00:00-04:00","event_time_end":"2026-07-06T13:00:00-04:00","event_time_end_last":"2026-07-06T13:00:00-04:00","gmt_time_start":"2026-07-06 15:00:00","gmt_time_end":"2026-07-06 17:00:00","gmt_time_end_last":"2026-07-06 17:00:00","rrule":null,"timezone":"America\/New_York"},"location":"TSRB523A + Remote ","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":""}},"690761":{"#nid":"690761","#data":{"type":"event","title":"PhD Defense by Jacob N.

Conventional inverse design and topology optimization frameworks often assume ideal reproductions of as-designed geometries, while methods that address uncertainty often treat manufacturing variability as stochastic noise to be managed probabilistically rather than as structured geometric information to be directly encoded. As a result, current workflows struggle to deliver robust, uncertainty-aware designs where predicted properties remain accurate under real process variability. This dissertation introduces the Manufacturing-Aware Deviation Encoding (MADE) vector: a compact, empirically-derived descriptor that encodes the process-specific geometric deviation fingerprint, which can be embedded directly into surrogate modeling and the inverse design loop. MADE is derived from a minimal set of CT-extracted geometric deviation features that explain dominant variance in mechanical performance over a range of lattice geometries. Demonstrated on fused filament fabrication (FFF)-printed thermoplastic polyurethane (TPU) re-entrant auxetic lattice samples, this framework enables surrogate models that propagate manufacturing uncertainty through the inverse design loop, helping bridge the gap between computational design intent and reality.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECommittee\u003C\/strong\u003E\u003C\/p\u003E\u003Cdiv\u003E\u003Cul type=\u0022disc\u0022\u003E\u003Cli data-list-item-id=\u0022ee899613368c2998b1c177322c2ed64be\u0022\u003EProf. Karl Jacob \u2013 School of Materials Science and Engineering (advisor)\u003C\/li\u003E\u003C\/ul\u003E\u003C\/div\u003E\u003Cdiv\u003E\u003Cul type=\u0022disc\u0022\u003E\u003Cli data-list-item-id=\u0022edd028279ca0fa2dd63e6f028a6f12315\u0022\u003EProf. Hamid Garmestani \u2013 School of Materials Science and Engineering\u003C\/li\u003E\u003C\/ul\u003E\u003C\/div\u003E\u003Cdiv\u003E\u003Cul type=\u0022disc\u0022\u003E\u003Cli data-list-item-id=\u0022e62fd120f6c07e5f699183a2a1d7e156f\u0022\u003EProf. Donggang Yao \u2013 School of Materials Science and Engineering\u003C\/li\u003E\u003C\/ul\u003E\u003C\/div\u003E\u003Cdiv\u003E\u003Cul type=\u0022disc\u0022\u003E\u003Cli data-list-item-id=\u0022eda2ae5434b5ed15facfca9e6a3d1eedf\u0022\u003EProf. Seyed M.

The small air gaps that remain when the fit is imperfect can therefore dominate the acoustic performance. At high SPL, an additional dissipation mechanism becomes active in which incident acoustic energy is converted into vorticity at the sharp edges of a small opening and is then dissipated by viscosity, the same mechanism that governs acoustic liners, perforated plates, nozzles, and other small-aperture elements. This dissertation quantifies the acoustic dissipation of small, rigid-walled airborne leak paths under high-SPL excitation and resolves how the incident energy partitions between viscous attenuation and conversion into vorticity.\u003C\/p\u003E\u003Cp\u003EThe work combines three methods. A custom two-sided impedance tube measures acoustic absorption directly using an impulse technique that reaches peak levels above 150 dB at the test article, with O-ring face seals that make it suitable for small leak-path test articles. Direct numerical simulation is performed with the open-source, GPU-accelerated compressible-flow solver MFC, to which this work contributed an immersed-boundary treatment of complex geometries. Spectral modal analysis is then applied to the simulation data to separate the dissipation pathways.\u003C\/p\u003E\u003Cp\u003EUsing these methods, the dissertation first studies leakage in modeled earplug-canal geometries. Experiment and simulation cross-verify on a uniform leak path, reproducing the same spectral shape and SPL ordering of the reflection, transmission, and absorption coefficients. Two- and three-dimensional simulations of a nonuniform ill-fitting earplug then resolve substantial conversion of acoustic energy into vorticity around leak paths at high SPL, with the frequency dependence interpreted through the Strouhal number. To the author\u0027s knowledge, this is the first direct numerical evidence that the SPL-dependent vortex-formation mechanism documented for isolated slits and orifices activates under earplug-like leakage conditions. Because the modeled geometry omits soft-tissue compliance, contact mechanics, and the middle-ear termination, these results are interpreted at the mechanism level rather than as predictions for a specific human ear.\u003C\/p\u003E\u003Cp\u003EThe dissertation then resolves the mechanism in a canonical acoustically-driven slit. A direct numerical simulation database spanning incident sound pressure level, Strouhal number, and Reynolds number reveals two distinct absorption regimes: a vortex-dominated regime at high amplitude in which the Strouhal number is the primary controlling parameter, and a viscosity-dominated regime at low SPL in which the Reynolds number plays a comparable role. Spectral proper orthogonal decomposition separates, mode by mode and frequency by frequency, the kinetic-energy and viscous-loss contributions to the dissipation and links each to its coherent spatial structure, which the integrated absorption coefficient cannot resolve. The partition between the two pathways is governed by the coupled effect of the Strouhal number, the Reynolds number, the SPL, and the Keulegan-Carpenter number. A triadic orthogonal decomposition further identifies the nonlinear inter-frequency energy transfer, showing a forward cascade in which the forced fundamental feeds higher harmonics through near-mouth and corner-localized convection before viscous removal.\u003C\/p\u003E\u003Cp\u003EThese contributions trace a single physical picture from a motivating application to its underlying mechanism, quantify how high-SPL sound is dissipated at small rigid openings, and provide a frequency- and space-resolved basis for the design of leak paths, slit resonators, and related small-aperture acoustic elements.\u201d\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EImpact of Leakage due to Ill-fitting Earplugs on the Dissipation of High-Amplitude Sound into Vorticity\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Impact of Leakage due to Ill-fitting Earplugs on the Dissipation of High-Amplitude Sound into Vorticity"}],"uid":"27707","created_gmt":"2026-06-17 13:28:59","changed_gmt":"2026-06-17 13:29:31","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-07-01T11:00:00-04:00","event_time_end":"2026-07-01T13:00:00-04:00","event_time_end_last":"2026-07-01T13:00:00-04:00","gmt_time_start":"2026-07-01 15:00:00","gmt_time_end":"2026-07-01 17:00:00","gmt_time_end_last":"2026-07-01 17:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Coda Building, Room C1315 (Grand Park), Georgia Tech","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":""}},"690787":{"#nid":"690787","#data":{"type":"event","title":"PhD Defense by Sedat Ors ","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003EPhD Candidate:\u003C\/strong\u003E\u0026nbsp;Sedat Ors\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EDissertation Title:\u003C\/strong\u003E\u0026nbsp;\u201cThree Essays on the Economic Impacts of Climate Change: Evidence from Migration, Health, and Agricultural Trade\u201d\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EAbstract:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EThis dissertation examines the economic impacts of climate change in T\u00fcrkiye across three related domains: internal migration, public health, and agricultural trade. Drawing on province-level and bilateral panel data and a range of econometric methods, the study analyzes how variation in temperature and precipitation influences economic behavior and economic outcomes.\u003C\/p\u003E\u003Cp\u003EThe first essay investigates the relationship between climate conditions and internal migration. Applying a structural gravity framework, it finds that higher temperatures increase out-migration, particularly in drought-prone provinces, indicating that climatic stress acts as an important push factor in migration decisions.\u003C\/p\u003E\u003Cp\u003EThe second essay examines the health consequences of climate change using a monthly province-level panel. The analysis identifies a U-shaped relationship between temperature and elderly mortality: both extreme cold and extreme heat increase mortality, while moderate temperatures are associated with lower mortality. The results further suggest that adaptation, proxied by residential electricity consumption, can attenuate vulnerability to temperature extremes.\u003C\/p\u003E\u003Cp\u003EThe third essay analyzes the effects of climate conditions on agricultural exports using both province-level and gravity-model approaches. Higher temperatures reduce export performance across vegetables, fruits, and cereals, with cereals emerging as the most climate-sensitive category, while precipitation generally supports exports. Consistent with gravity theory, an importer\u0027s GDP raises exports, and distance reduces them.\u003C\/p\u003E\u003Cp\u003ETogether, these essays show that climate change shapes economic outcomes through multiple, interconnected channels: it increases migration pressures, raises mortality risks, and reduces agricultural export performance.

Modeling transport in these applications is challenging because the dynamics are multiscale, involve several coupled processes, and can depend on interactions with nonporous regions. This dissertation develops a coarse-grained model from first principles for multiphase transport in channels with porous walls, motivated by temperature swing adsorption (TSA) carbon capture. The model begins with pore-scale physics, which are extended to the macroscopic scale through volume averaging. The model is then extended to describe gaseous species transport, carbon dioxide adsorption, liquid-water transport, phase change, and heat transfer. Reduced models based on rapid local equilibration are derived to address numerical stiffness while preserving the relevant macroscopic dynamics. The resulting model is applied to multiple stages of TSA operation to identify characteristic time scales. The results show that diffusion through the porous wall plays a central role in setting these time scales, together with advection in the adjacent nonporous flow regions. Accordingly, this dissertation demonstrates how multiscale physics can be integrated into a tractable continuum model for predicting multiphase behavior in porous systems.\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\u003EA Model for Multiphase Transport in Channels with Porous Walls\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"A Model for Multiphase Transport in Channels with Porous Walls"}],"uid":"27707","created_gmt":"2026-06-17 13:04:13","changed_gmt":"2026-06-17 13:05:23","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-06-29T12:30:00-04:00","event_time_end":"2026-06-29T14:00:00-04:00","event_time_end_last":"2026-06-29T14:00:00-04:00","gmt_time_start":"2026-06-29 16:30:00","gmt_time_end":"2026-06-29 18:00:00","gmt_time_end_last":"2026-06-29 18:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Howey N201\/202","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":""}},"690762":{"#nid":"690762","#data":{"type":"event","title":"PhD Defense by Danielle Grau","body":[{"value":"\u003Cdiv\u003E\u003Cp\u003E\u003Cstrong\u003ETitle:\u003C\/strong\u003E PHYSICS-BASED APPROACHES TO INCLUDING SUPRAGLACIAL MELT\u0026nbsp;\u003C\/p\u003E\u003C\/div\u003E\u003Cdiv\u003E\u003Cp lang=\u0022EN-US\u0022\u003ELAKES IN EARTH SYSTEM MODELS\u0026nbsp;\u003C\/p\u003E\u003Cp lang=\u0022EN-US\u0022\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp lang=\u0022EN-US\u0022\u003E\u003Cstrong\u003EDanielle Grau\u0026nbsp;\u003C\/strong\u003E\u003C\/p\u003E\u003Cdiv\u003E\u003Cp\u003E\u003Ca href=\u0022mailto:\u0022 title=\u0022mailto:\u0022\u003Edgrau7@gatech.edu\u003C\/a\u003E\u003C\/p\u003E\u003C\/div\u003E\u003Cdiv\u003E\u003Cp\u003E\u003Ca href=\u0022https:\/\/nam12.safelinks.protection.outlook.com\/?url=https%3A%2F%2Fdgrau13.github.io%2F\u0026amp;data=05%7C02%7Cfkhan47%40gatech.edu%7C891e71392c404df91b7508decbaf08db%7C482198bbae7b4b258b7a6d7f32faa083%7C1%7C0%7C639172149923251964%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C\u0026amp;sdata=7fYrpIjzqpi9lMVJTwtZgZF5fZMMLenKwWG2J2Ai2SI%3D\u0026amp;reserved=0\u0022 rel=\u0022noopener noreferrer\u0022 target=\u0022_blank\u0022 title=\u0022Original URL: https:\/\/dgrau13.github.io\/.

These features have been observed across the fringes of Greenland, the Antarctic Peninsula, and several ice shelves in Antarctica. A large-scale ice shelf collapse event in April 2002 of Larsen B ice shelf is believed to have been caused by an abundance of supraglacial melt lakes that formed on the surface in the months prior inducing a large-scale hydrofracture event. Since this large collapse event, the ice shelf has not been able to recover since. Despite the large impact that supraglacial melt lakes have on glacier processes, these features are not well represented in large scale earth system models. This thesis bridges this gap in knowledge by developing a new, easily-adaptable parameterization of the mean area fraction and depth of supraglacial melt lakes on self-affine glacial surfaces. These parameterizations are implemented within a large scale ice-sheet model. Simulations of the future evolution of the Antarctic Ice Sheet show that including the effect of supraglacial melt lake depth on hydrofracture-driven calving accelerates project future ice sheet mass loss by nearly 100% compared to simulations without calving and 30% compared to simulations that do not represent the depth of supraglacial lakes.\u0026nbsp;\u003C\/p\u003E\u003C\/div\u003E\u003C\/div\u003E\u003C\/div\u003E\u003C\/div\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EPHYSICS-BASED APPROACHES TO INCLUDING SUPRAGLACIAL MELT\u003Cbr\u003ELAKES IN EARTH SYSTEM MODELS\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"PHYSICS-BASED APPROACHES TO INCLUDING SUPRAGLACIAL MELT LAKES IN EARTH SYSTEM MODELS"}],"uid":"36872","created_gmt":"2026-06-16 17:17:35","changed_gmt":"2026-06-16 17:24:16","author":"fkhan47","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-06-26T10:00:47-04:00","event_time_end":"2026-06-26T12:00:47-04:00","event_time_end_last":"2026-06-26T12:00:47-04:00","gmt_time_start":"2026-06-26 14:00:47","gmt_time_end":"2026-06-26 16:00:47","gmt_time_end_last":"2026-06-26 16:00:47","rrule":null,"timezone":"America\/New_York"},"location":"ES\u0026T L1205","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":""}},"690760":{"#nid":"690760","#data":{"type":"event","title":"PhD Defense by Jingyuan Shen\u00a0","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003EPh.D. Proposal Defense -

Cultivating a future-ready workforce requires early educational interventions, but high school students often lack exposure to the AEC industry as a technology-enabled and socially meaningful career path. Furthermore, existing outreach efforts frequently treat sustainability education and career exposure as separate entities, leaving a critical gap in how we jointly support environmental comprehension and vocational development. To bridge this gap, this study investigates GreenBuildVR, an interactive virtual reality-based intervention designed for high school students. Grounded in the Green Building Literacy framework and Social Cognitive Career Theory (SCCT), this study outlines four core objectives: 1) evaluating the intervention\u2019s impact on students\u2019 sustainability literacy; 2) assessing its effect on sustainable construction career development; 3) examining the predictive relationship between these two domains; and 4) exploring how these effects vary across contextual factors. The empirical assessment will be conducted with high school students in a summer camp setting using a pretest\u2013posttest intervention evaluation design. This research is expected to yield an empirically grounded understanding of how VR-based intervention supports both sustainability literacy and career development among high school students. It will clarify how literacy-related constructs are associated with SCCT-based career development constructs and how student background, prior experience, and VR-related learning experience factors moderate intervention effects. The study contributes by integrating sustainability literacy and career development into a coherent VR-based intervention model, offering a construct-measure framework for pre-college sustainable construction education, and providing design guidance for AEC outreach programs seeking to support future sustainable workforce pathways.\u003C\/p\u003E\u003C\/div\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EFostering Sustainability Literacy and Construction Career Development Through Interactive Virtual Reality: An Experiential Learning Approach for High School Students\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Fostering Sustainability Literacy and Construction Career Development Through Interactive Virtual Reality: An Experiential Learning Approach for High School Students"}],"uid":"36872","created_gmt":"2026-06-16 17:01:53","changed_gmt":"2026-06-16 17:08:02","author":"fkhan47","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-06-30T11:00:40-04:00","event_time_end":"2026-06-30T13:00:40-04:00","event_time_end_last":"2026-06-30T13:00:40-04:00","gmt_time_start":"2026-06-30 15:00:40","gmt_time_end":"2026-06-30 17:00:40","gmt_time_end_last":"2026-06-30 17:00:40","rrule":null,"timezone":"America\/New_York"},"location":"Caddell Building, Flex Space","extras":[],"related_links":[{"url":"https:\/\/teams.microsoft.com\/meet\/253269875550033?p=hFBtigRwV6yXosWAkW","title":"Teams Meeting Link"}],"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":""}},"690759":{"#nid":"690759","#data":{"type":"event","title":"PhD Defense by DaEun Kim","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003EName: DaEun Kim\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ESchool of Psychology- Ph.D Dissertation Defense Meeting\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EDate: Friday June 26, 2026\u003C\/p\u003E\u003Cp\u003ETime: 10:00 \u2013 12:00\u003C\/p\u003E\u003Cp\u003ELocation: Virtual\u003C\/p\u003E\u003Cp\u003EZoom Link: \u003Ca href=\u0022https:\/\/nam12.safelinks.protection.outlook.com\/?url=https%3A%2F%2Fgatech.zoom.us%2Fj%2F96632680979\u0026amp;data=05%7C02%7Cfkhan47%40gatech.edu%7Cf6a12cc4a7824c6fc11908decbaefd2c%7C482198bbae7b4b258b7a6d7f32faa083%7C1%7C0%7C639172149671996835%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C\u0026amp;sdata=yW69Kj3yZRFM2KWRaemtVGQWtXEQilWAVPOlZglZcBM%3D\u0026amp;reserved=0\u0022 rel=\u0022noopener noreferrer\u0022 target=\u0022_blank\u0022 title=\u0022Original URL: https:\/\/gatech.zoom.us\/j\/96632680979.

However, most research primarily focuses on between-individual similarities in how past and future events are experienced (phenomenology). There has been less attention to within-individual similarity between past and future thinking, as well as to other aspects that may demonstrate a parallel. Drawing on the Self-Memory System model and narrative identity research, the current research examined the role of self in autobiographical past and future thinking, specifically whether having a clear and stable sense of self correlates with greater intraindividual similarities of past and future thinking. Study 1 revealed that self-concept clarity was significantly associated with phenomenological similarities and marginally associated with motivational similarities, which paved ways for an experiment in Study 2. Study 2 experimentally manipulated self-concept clarity and tested its impact on the parallel of autobiographical past and future events among younger and older adults. The experimental effect on intraindividual similarities of past and future thinking was not found. Instead, self-concept clarity assessed at baseline appeared to predict greater phenomenological and reasoning in mental time travel, regardless of age. Self-concept clarity also predicted greater achievement and relationship motivations in younger adults\u2019 autobiographical events. These findings suggest that individual differences in the experience of and reflection on mental time travel may be grounded in individual differences in self-representations.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003ESelf-Representation Stability and Intraindividual Similarities of Autobiographical Past and Future Thinking\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Self-Representation Stability and Intraindividual Similarities of Autobiographical Past and Future Thinking"}],"uid":"36872","created_gmt":"2026-06-16 16:56:46","changed_gmt":"2026-06-16 16:59:43","author":"fkhan47","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-06-26T10:00:35-04:00","event_time_end":"2026-06-26T12:00:35-04:00","event_time_end_last":"2026-06-26T12:00:35-04:00","gmt_time_start":"2026-06-26 14:00:35","gmt_time_end":"2026-06-26 16:00:35","gmt_time_end_last":"2026-06-26 16:00:35","rrule":null,"timezone":"America\/New_York"},"location":"Virtual","extras":[],"related_links":[{"url":"https:\/\/nam12.safelinks.protection.outlook.com\/?url=https%3A%2F%2Fgatech.zoom.us%2Fj%2F96632680979\u0026data=05%7C02%7Cfkhan47%40gatech.edu%7Cf6a12cc4a7824c6fc11908decbaefd2c%7C482198bbae7b4b258b7a6d7f32faa083%7C1%7C0%7C639172149671996835%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C\u0026sdata=yW69Kj3yZRFM2KWRaemtVGQWtXEQilWAVPOlZglZcBM%3D\u0026reserved=0","title":"Virtual"}],"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":""}},"690738":{"#nid":"690738","#data":{"type":"event","title":"Ph.D. Defense Announcement - Yuichiro Aoyama","body":[{"value":"\u003Cdiv\u003E\u003Cstrong\u003ETitle: \u003C\/strong\u003EEntropic-Regularized Second-Order Dynamic Optimization\u003C\/div\u003E\u003Cdiv\u003E\u003Cstrong\u003EDate:\u003C\/strong\u003E\u0026nbsp;June 26, 2026\u003C\/div\u003E\u003Cdiv\u003E\u003Cstrong\u003ETime:\u003C\/strong\u003E\u0026nbsp;12:00 PM\u003C\/div\u003E\u003Cdiv\u003E\u003Cstrong\u003ELocation:\u003C\/strong\u003E\u0026nbsp;\u003Ca href=\u0022https:\/\/teams.microsoft.com\/meet\/22451334760459?p=xtoZ7nmnK1RtTcKEmR\u0022 id=\u0022OWA80802ac0-25e5-885c-374f-90469306498c\u0022 rel=\u0022noopener noreferrer\u0022 target=\u0022_blank\u0022 title=\u0022https:\/\/teams.microsoft.com\/meet\/22451334760459?p=xtoZ7nmnK1RtTcKEmR\u0022\u003ECoda Conference Room C1115\u003C\/a\u003E\u003C\/div\u003E\u003Cdiv\u003E\u0026nbsp;\u003C\/div\u003E\u003Cdiv\u003EYuichiro Aoyama\u003C\/div\u003E\u003Cdiv\u003EMachine Learning PhD Candidate\u003C\/div\u003E\u003Cdiv\u003ESchool of Aerospace Engineering\u003C\/div\u003E\u003Cdiv\u003EGeorgia Institute of Technology\u003C\/div\u003E\u003Cdiv\u003E\u0026nbsp;\u003C\/div\u003E\u003Cdiv\u003E\u003Cstrong\u003ECommittee\u003C\/strong\u003E\u003C\/div\u003E\u003Cdiv\u003EDr. Evangelos A.

While classical second-order methods like Differential Dynamic Programming (DDP) offer fast local convergence, they easily get trapped in local minima due to their reliance on local information. Although purely sampling-based methods bypass the locality issue, they suffer from high sample complexity and noisy decision-making. To bridge this gap, this work leverages the Maximum Entropy DDP (ME-DDP) framework, in which a structured exploration covariance naturally arises from entropic regularization, balancing second-order local exploitation with robust trajectory perturbation. We extend this mechanism beyond standard Shannon entropy to generalized representations, detailing the development of Tsallis entropy and Stein Variational DDP (SV-DDP) to maintain policy diversity without sacrificing optimization structure. Benchmarked against Model Predictive Path Integral (MPPI) variants within a Model Predictive Control (MPC) framework, the proposed algorithms demonstrate superior overall performance, with their practical robustness validated through hardware experiments on a quadrotor navigation task in cluttered environments.\u003C\/div\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EEntropic-Regularized Second-Order Dynamic Optimization\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Entropic-Regularized Second-Order Dynamic Optimization"}],"uid":"36872","created_gmt":"2026-06-12 15:26:07","changed_gmt":"2026-06-12 15:33:34","author":"fkhan47","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-06-26T12:00:00-04:00","event_time_end":"2026-06-26T14:00:49-04:00","event_time_end_last":"2026-06-26T14:00:49-04:00","gmt_time_start":"2026-06-26 16:00:00","gmt_time_end":"2026-06-26 18:00:49","gmt_time_end_last":"2026-06-26 18:00:49","rrule":null,"timezone":"America\/New_York"},"location":"Coda Conference Room C1115 or Zoom Link","extras":[],"related_links":[{"url":"https:\/\/teams.microsoft.com\/meet\/22451334760459?p=xtoZ7nmnK1RtTcKEmR","title":""}],"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":""}}}
