About Me

Hi! I’m Can Chen, a first-year PhD student in Data Science at the Halıcıoğlu Data Science Institute, University of California San Diego. I’m fortunate to be advised by Prof. Jun-Kun Wang.

My research interest lies in online learning. Recently, I am working on the LLM-generated text detection by online optimization.
