Welcome to my homepage!

I’m a Computer Science MSc student at The University of British Columbia, working with Prof. Ivan Beschastnikh and Prof. Mathias Lécuyer. I completed my Bachelor’s in Computing at The Hong Kong Polytechnic University.

My research interests involve distributed system, cloud computing and machine learning. In 2019, I did an internship at Microsoft Research Asia (MSRA), working with Dr. Yang Chen. We worked on Forerunner, a novel technique that accelerates block validation process in Ethereum. In 2020, I finished my undergraduate thesis under the supervision of Prof. Song Guo. My thesis was about developing new compression techniques in distributed machine learning. Currently, we are working on evaluating compression techniques in Federated Learning at UBC with Huawei.

I love solving algorithm problems. In past years, I participated in a number of programming contests, such as ACM ICPC Regional Contest, IEEEXtreme, and National Olympiad in Informatics in Province. I am also an experienced codeforces user :).
