Ph.D. Candidate University of California, Santa Cruz
About Me
I am a fourth year Ph.D. in the Computer Science and Engineering Department at the University of California, Santa Cruz, fortunate to be advised by Professor Yang Liu. My research focuses on the social aspect of machine learning, taking into account human decision subjects' responses when developing algorithmic systems. I was a student researcher at Google Brain hosted by Ehsan Amid in the summer of 2022. Starting from Fall 2023, I will be supported by the Chancellor’s Dissertation-Year Fellowship.
I received a MS in Statistics at Stanford University in 2019, where I worked with Professor Johan Ugander on node classification problem using semi-supervised learning.
Before that, I received my BS in Energy and Resources Engineering and BA in Economics from Peking University in 2016.
I received the Chancellor’s Dissertation-Year Fellowship from UCSC (only one recipient in the School of Engineering)!
One paper got accepted by TMLR!
One paper got accepted by ICML 2023 (see you in Hawaii)!
