Pingchuan Ma

I am a third year Ph.D. candidate at Department of Computer Science and Engineering, Hong Kong University of Science and Technology (HKUST), under the supervision of Prof. Shuai Wang. I received my B.Eng. from Beijing Electronic Science and Technology Institute. My research interests include data management, trustworthy AI (causality, privacy, fairness, etc.) and software engineering.
