The core idea is that human AI interaction is a communication problem in two directions. In the model to human direction, explanations must compress the model\u2019s internal reasoning into a form that preserves what a person needs to judge, trust, or correct the output. In the human to model direction, prompts must compress the user\u2019s intent into a form that is sufficient to guide model behavior without adding redundant or conflicting signal. This proposal argues that necessity and sufficiency are the right principles for analyzing both directions under one theory. A representation is necessary if removing it changes the outcome, and sufficient if providing it can produce the desired outcome. Building on this view, the research first develops causal, interventional measures of necessity and sufficiency and uses them to study existing explanation methods, showing in preliminary tabular experiments that highly ranked features are not always both necessary and sufficient. It then extends the framework to image models, where it investigates whether standard evaluation metrics truly measure information that survives the model\u2019s internal compression. Finally, it applies the same framework to interactive segmentation, where prompts are analyzed as units of information transfer, classified by their contribution, and selected actively through predictive disagreement using a Bayesian extension of SAM.

One of the main promises of multimodal learning is to combine data from multiple sensing modalities via the use of their complementary information for a targeted downstream task. However, the benefits of multimodal fusion are typically demonstrated when training and evaluation data share the same distribution. Domain generalization methods address distribution shift for single-modality systems, but do not account for the interactions that arise when multiple encoders are trained jointly through a shared objective. While information-theoretic frameworks provide a principled decomposition of task-relevant information into redundant, unique, and synergistic components, they assume stationary distributions. How this information structure changes under domain shift, and how such changes interact with joint optimization, remain unexplored. This proposal addresses this gap by analyzing how each component of multimodal information varies across domains and by developing training procedures that preserve robust representations under domain shift. Preliminary research establishes that multimodal fusion improves accuracy under matched conditions, but this advantage diminishes under distribution shift.

Embedded inductors, essential for efficient power delivery, must maintain high performance at elevated temperatures, minimizing Joule heating and inductance loss. Designing such components requires robust multiphysics modeling, yet conventional methods are computationally intensive. This thesis proposes solutions for both efficient embedded inductor design and computationally efficient multi-physics modeling. A dual-core inductor design is introduced, featuring two coils separated by magnetic cores and an air gap. This configuration enhances saturation current capacity and overall performance, mitigating the common low-saturation current limitation in embedded inductors. For multi-physics modeling, an augmented computational method is developed, using a frequency-domain approach with Fourier series\u2013based Toeplitz matrices. This method provides a unified framework for transient electrical simulations and steady-state thermo-mechanical analysis, representing time-varying system elements in the frequency domain to improve stability and efficiency.

Tasks such as object detection from image rely on additional sensors and tasks such as natural language processing performed using large language models (LLMs) require efficient access to large memory capacity. As a result, they require close interconnection between different components for efficient data and signal movement. Heterogeneous integration has been proposed recently to address such concerns. This dissertation proposes designs for various problems ranging from sensing-based edge technologies to large server-based hardware accelerators for LLMs. The work proposes designs and analysis different packaging schemes depending upon the requirements. It proposes heterogeneous integration of different components including emerging memories to be able to design efficient hardware for such applications. Further, this study addresses thermal challenges associated with such heterogeneous integrated designs. Evaluations are performed to compare various designs and compared against the state-of-the-art. Further, the study proposes path for designing and evaluating future memories and interconnect technologies, providing design insights into various bottlenecks and an evaluation methodology for performing an electrical-thermal system-level co-design. Building upon the CIS and LLM accelerator designs, this dissertation develops a systematic system-technology co-optimization (STCO) methodology for evaluating advanced packaging configurations. The methodology is applied to compare 2.5D interposer, 3D HBM-on-logic, and selective layer transfer (SLT) integration for LLM accelerators across inference and training workloads. Detailed thermal and power delivery analysis is performed for 3D stacked HBM and compute accelerators, examining the trade-offs between memory-on-logic and logic-on-memory configurations. A hybrid design combining elements of both approaches is proposed and shown to achieve favorable thermal profiles while maintaining high memory bandwidth. Finally, a generalized software-hardware co-design framework, NS-AP (NeuroSim for Advanced Packaging), is developed that extends the analysis to arbitrary packaging configurations and workloads.

Although coronary catheter angiography is the gold standard for CVD evaluation, it is invasive and relatively expensive. In contrast, cardiac computed tomography angiography (CTA) is a more practical alternative because it is less invasive, more affordable, and more accessible. Despite these advantages, its image quality is often degraded by motion artifacts from the continuously beating heart. To reduce these artifacts, CTA commonly relies on electrocardiogram (ECG) gating to estimate cardiac quiescence, defined as the period of minimal cardiac motion. However, ECG reflects electrical activity rather than mechanical motion, making it an indirect surrogate for identifying true quiescent periods. Mechanical signals such as seismocardiography (SCG) and ultrasound (US) therefore offer promising alternatives for improving quiescence prediction. Although ultrasound has previously shown promise for identifying cardiac quiescence, its use during CT acquisition was limited by streak artifacts from conventional transducers. This dissertation develops multimodal gating frameworks to improve cardiac quiescence prediction for CTA. First, an SCG-ECG prediction framework was extended with a regression-based artificial neural network and evaluated using patient data, with diagnostic image quality assessed through a blinded reader study. Second, a deep learning-based US-ECG gating framework incorporating convolutional neural networks was developed and evaluated using multimodal datasets acquired from a dynamic heart motion phantom, enabling multimodal data acquisition under varied motion conditions. Third, the effect of US-ECG-based quiescence prediction on diagnostic image quality was assessed through a phantom-based CT reader study comparing reconstructed CTA images with conventional gating strategies. These contributions highlight the potential of multimodal gating to improve cardiac CTA and advance translation toward more reliable clinical imaging workflows.\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Multimodal Predictive Frameworks for Cardiac Computed Tomography Gating "}],"uid":"28475","created_gmt":"2026-04-03 22:12:52","changed_gmt":"2026-04-03 22:14:08","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-04-21T12:00:00-04:00","event_time_end":"2026-04-21T14:00:00-04:00","event_time_end_last":"2026-04-21T14:00:00-04:00","gmt_time_start":"2026-04-21 16:00:00","gmt_time_end":"2026-04-21 18:00:00","gmt_time_end_last":"2026-04-21 18:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Room 4222, Price Gilbert","extras":[],"related_links":[{"url":"https:\/\/gatech.zoom.us\/j\/96448479210?pwd=EfyBLKcEaxXpzEcndUzHTNz2vwu1aQ.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":""}},"689460":{"#nid":"689460","#data":{"type":"event","title":"Ph.D. Proposal Oral Exam - Hua Chen","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003ETitle:\u0026nbsp; \u003C\/strong\u003E\u003Cem\u003EEfficient Power Delivery Using High-voltage DC-DC Converters for Data-Centers\u003C\/em\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECommittee:\u0026nbsp;\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EDr.\u0026nbsp;Raychowdhury, Advisor\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EDr. Li, Chair\u003C\/p\u003E\u003Cp\u003EDr. Sathe\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EThe objective of this research is to develop high-voltage hybrid DC-DC converters with compact designs that achieve high power density for data center applications.
