About

I am a PhD candidate in the Statistical and Relational Artificial Intelligence (StarAI) lab at UCLA, advised by Guy Van den Broeck. My research interests are in tractable probabilistic models, graphical models, knowledge compilation, and trustworthy AI/ML (robustness, fairness, explainability, etc.).
