Zach (Zhen) Xu

Hey I’m Zach! I am a first-year CS PhD student at University of Chicago, advised by Ce Zhang.
My research interests are centered on large language model with a recent focus on agentic systems, test-time scaling and interdisciplinary scientific applications.
I also contributed to the Codabench which is one of the most commonly used open source competition platforms accoding to ML Contests.
I am always excited to chat about interesting projects. Feel free to reach out!
