Welcome to my homepage!

I’m a first-year PhD student in Computer Science and Engineering at University of Michigan, Ann Arbor, advised by Prof. Mosharaf Chowdhury. 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.

My current research interests involve distributed system, cloud computing and machine learning. In my MSc work, I proposed GlueFL, a federated learning framework designed to optimize downstream bandwidth. Prior to this, I finished my undergraduate thesis under the supervision of Prof. Song Guo. My thesis was about developing new compression techniques in distributed machine learning. Even before, I did an internship at Microsoft Research Asia (MSRA), working with Dr. Yang Chen. We worked on Forerunner, a novel computing framework that leverages speculative execution to accelerate transaction processing on Ethereum.
