Short Bio: I am a Post-doctoral Fellow at the CSE Department of HKUST. I am working in the Cybersecurity Lab led by Prof. Charles Zhang. I am also collaborating with Prof. S.C. Cheung, the leader of the CASTLE Lab. My research interests include software testing and analysis, adaptive systems, mobile computing, and software security. My current work focuses on designing techniques to help developers build green, fast, and reliable mobile software. The tools I built have helped real-world Android developers locate 150+ previously-unknown bugs in their apps. I obtained my B.Sc. degree in Computer Science with the Outstanding Graduate honor from Nanjing University in 2010, and my Ph.D. degree in Computer Science and Engineering (thesis) from HKUST in 2015. I was a visiting student at Wilfrid Laurier University in 2009.
