I am an Assistant Professor at the Computer Science Department in The University of Hong Kong. I lead the HKUS3 Lab, where we design and build systems to automatically detect and prevent attacks in software and systems. Our research interests encompass program analysis, software debloating, dynamic/hybrid testing, and binary code analysis.

We have a number of openings for Ph.D. students, research assistants, and postdoctoral researchers. Please drop me an email if you are interested in software and system security.
