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 passing tests, interleaving learning, learning by self-explanation, small-group learning, learning by teaching, learning by ignoring, etc., and their applications in healthcare. Please refer to this monograph and project page for details.
