My research is in computer security and privacy. More specifically, I am interested in designing inference attacks to quantify information leakage of a system about its sensitive inputs. I also design privacy-preserving mechanisms to mitigate such inference attacks. My current focus is on machine learning and data privacy.

Open Positions

Two open positions for PhD students. Candidates need to get admission from the doctoral program. International students can also apply for the SINGA award (next deadline: 1 Jan 2018).

Multiple open positions for interns and research assistants.

If you are interested, please send me your CV along with a concise description of your research interests.
