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.

[Competition@IJCAI] We are organizing the 1st Learning and Mining with Noisy Labels Challenge (LMNL) at IJCAI-ECAI 2022. The competition includes two tasks: learning with noisy labels, and noisy labels detection. We are calling for competition participants and program committees. We will be giving out best performance and best paper awards (sponsored by Snorkel AI!).
