I am a third-year Computer Science PhD student at UCLA, advised by Professor Bolei Zhou and Professor Jiaqi Ma. My research is supported by Qualcomm Innovation Fellowship.

Previously, I received my M.S. and B.A. in Computer Science at UC Berkeley where I was fortunate to work with Professor Masayoshi Tomizuka, Professor Allen Yang, and Professor Constance Chang-Hasnain. I was also a research intern at Qualcomm and Honda Research Institute (HRI) before.

My research focuses on closed-loop, autonomous agent improvement, with the long-term goal of enabling reliable recursive self-improvement. I study self-improvement mechanisms, agent monitoring and auditing, and adaptive evaluation frameworks that evolve alongside agent capabilities.

I value mentorship deeply, and I have been fortunate to mentor many talented students during my PhD. Please see the Mentorship page for more details.
