Assistant Professor, Department of Electrical and Computer Engineering

Affiliated Faculty, AI Group in the Department of Computer Science and Engineering

University of California San Diego

I obtained my PhD from the Machine Learning Department, School of Computer Science, Carnegie Mellon University. My research interests mainly lie in machine learning inspired by humans’ learning skills (especially classroom learning skills), such as learning by self explanation, small-group learning, learning by teaching, etc., and their applications in Large Language Models, Foundation Models, and Healthcare. Here is a summary of research outcome.

I am looking for highly-motivated PhD and master students to join my group. I am also looking for research interns for summer.
