Hi There

Hi there! I am a 2nd-year PhD student in Computer Science, at University of California, Los Angeles, advised by Prof. Saadia Gabriel. Previously I received my Master’s degree in CS at Univeristy of Illinois Urbana-Champaign, advised by Prof. Heng Ji and Prof. Hao Peng. I received undergraduate degrees in both Computer Science and Mathematics from University of Massachusetts, Amherst. I worked at the Information Fusion Lab advised by Prof. Ina Fiterau and the TRIPODS Institute for Theoretical Foundations of Data Science at UMass Amherst advised by Prof. Yulong Lu as a research intern.

Research Interests

I’m broadly interested in Large Language Models and agentic systems powered by them. Most recently I’ve been working extensively on web agents, self-evolving models, and memory mechanisms of LLM agents. During my PhD I’ve worked on multi-agent simulation systems (EMNLP 2025 Oral, NeurIPS 2025) and LLM safety (COLM 2025). In more distant past I’ve worked on benchmarking and evaluations (NeurIPS 2024), video-language models (NeurIPS 2023), and multilingual NLP (ACL workshop 2023).
