About Me

I’m an Assistant Professor of Computer Science and Engineering at UC Santa Cruz. My research interests are crowdsourcing and algorithmic fairness, both in the context of machine learning. The central question associated with my work is learning from dynamic and noisy data.

Previously I was holding a postdoctoral fellow position at Harvard University. I have a Ph.D. from the University of Michigan, Ann Arbor and a B.Sc. from Shanghai Jiao Tong University, China.

My research is generously supported by the National Science Foundation (by their CORE, FAI, CAREER and TRIPOS programs), Office of Naval Research (Basic AI Research), Amazon, UC Santa Cruz and CROSS. I was partially supported by the DARPA SCORE program.

ByteDance AI Lab I am currently on leave from UCSC and leading the Machine Learning Fairness team at ByteDance. We are looking to hire full-time research scientists, see here and here. Our UK team is also hiring interns, see here. Our Mountain View office will be looking for interns for 2023 summer too - stay tuned! If you’d like to discuss any of these career opportunities, I can be reached at .
