About Me
-
I am a Research Group Leader in the Social Foundations of Computation Department at the Max Planck Institute for Intelligent Systems in Tübingen, Germany, hosted by Professor Moritz Hardt.
I completed my Ph.D. from the Computer Science and Engineering Department at the University of California, Santa Cruz, where I was 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 and Rohan Anil in the summer of 2022. I was 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.
Here's my CV (last updated May 2024) and contact info.
News:
- [May 2024] I successfully defended my PhD thesis!
- [May 2024] One paper got accepted to ICML! See you in Austria soon!
