Professional Summary
Research Scientist in Explainable AI specializing in attribution methods and faithfulness metrics for vision, language, and multimodal transformers. Author of 7 peer-reviewed publications at AAAI, ICLR, IJCAI, and AISTATS, with state-of-the-art contributions to attribution methods and metrics, robustness, and out-of-distribution detection. My work emphasizes principled, quantitative evaluation and reproducible research, alongside mentoring and open research software development
Experience
-
2024 - present Gainesville, FL
Graduate Research Assistant
AI and Computing Lab
Conduct research in Explainable AI (XAI), developing attribution methods and evaluation metrics for deep neural networks with applications in adversarial robustness and out-of-distribution detection for high-stakes deployments.
- Developed Metric-Driven Attributions (MDA) framework outperforming 7 ViT attribution methods by 12% across 12 metrics on ImageNet, establishing state-of-the-art in transformer interpretability (ICLR 2025).
- Developed attribution graphs to enable an understanding of how causal information propagates from an LLM prompt to its generation, improving faithfulness on SOTA LLMs by 20% on average (Preprint 2025).
- Pioneered Magnitude Aligned Scoring (MAS) XAI evaluation benchmark 4x more sensitive to attribution changes, 2x more consistent, 1.6x more baseline-invariant than existing metrics (IJCAI 2024).
- Designed Integrated Decision Gradients (IDG), a novel path-based attribution to address gradient saturation in deep networks, achieving state-of-the-art performance (AAAI 2024).
- Created InFlow, an information flow-based explanation framework for ViTs outperforming 6 attribution methods by up to 18% in eight metrics (AISTATS 2025).
- Developed attribution-based adversarial detection system achieving 99% accuracy classifying pixel and patch attacks in CNNs trained on ImageNet; supported by DARPA (MILCOM 2023).
- Invited talk: “Towards Effective XAI of Modern Models”. Prince of Songkla University, Thailand (2024).
- Best Poster Award: 2025 Nelms IoT Conference.
- Mentored 12 undergraduate researchers; outcomes include 3 honors theses and 2 graduate admissions.
- Reviewed for ICLR, ICML, IJCAI, CVPR, ECCV, and JMLR.
- Volunteered for the 2024 and 2025 Nelms IoT Conferences.
-
