I am an Assistant Professor in Information Systems at Naveen Jindal School of Management, UT Dallas. I received my PhD degree in Information, Risk, and Operations Management from UT Austin. I received my master’s degree in Statistics from Univerisity of Michigan, and bachelor’s degree in Statistics from the School of the Gifted Young at University of Science and Technology of China (USTC). I previously worked at Netflix Research (advised by James Mclnerney and Nathan Kallus), Harvard University (advised by Himabindu Lakkaraju), IBM Research (advised by Wei Sun, Max Biggs, and Markus Ettl), Tencent, and Amazon.
Research
My research focuses on advancing human-centered machine learning, with an emphasis on enhancing the robustness, interpretability, adaptability, and privacy of different kinds of ML/AI models, including foundational models. Many of my research aim to answer these questions:
- How to develop algorithms that can work better with humans?
- How to design more effective human-AI systems and AI explanations?
- How to assess individual preferences or algorithm performance in the presence of missing counterfactuals?
