Welcome to my homepage!

I’m a third-year PhD student in Computer Science and Engineering at University of Michigan, Ann Arbor, advised by Prof. Mosharaf Chowdhury. My current research interests involve Agentic AI Systems, Multimodal Model Training and Distributed Machine Learning.

Before UMich, I completed my MSc in Computer Science at University of British Columbia, working with Prof. Ivan Beschastnikh and Prof. Mathias Lécuyer. I obtained my Bachelor’s in Computing at Hong Kong Polytechnic University, under the supervision of Prof. Song Guo.
