. I was very fortunate to have the late Professor
as my advisor during my first two years at Yale. Before coming to Yale, I obtained my B.Eng. from
with a dual B.S. from
.
My research interests have evolved with the rapid advancement of AI. Currently, I focus on (1) building foundation models that deliver expert-level reasoning, multimodal understanding, and knowledge-intensive capabilities for high-stakes domains such as science, (2) developing scalable, expert- and community-driven evaluation and alignment methods that make expert-domain model behavior measurable, comparable, and improvable, and (3) quantifying and mitigating societal and user-facing risks in real workflows, and designing human-AI systems that meet real user needs for responsible deployment.
