About

Hi, I am a first-year PhD student in Computer Science at the University of California, Los Angeles. I am advised by Yizhou Sun and also work closely with Jason Cong. Previously, I received both my bachelor's and master's degrees in Computer Science and Technology from Zhejiang University, where I was advised by Yang Yang. I am a (inactivate) participant in Competitive Programming. In online programming contests, I use HbFS- as my ID, which comes from the acronym of the song "Harder, Better, Faster, Stronger" by Daft Punk.
