Bio

Hi! I'm a third-year PhD student in Computer Science and Engineering at Santa Clara University, working under the guidance of Professor Yi Fang. Prior to joining SCU, I completed my undergraduate degree in Physics at the University of California, Davis. I'm currently on track to graduate in 2028.

Research

My research focuses on information retrieval, particularly in how to leverage large language models (LLMs) for information retrieval tasks. I'm also interested in self-improving AI methods.
