Short Intro

Hi! My name is Shufan Zhang. I am currently a first-year PhD student in Computer Science at University of Waterloo (Waterloo, Canada), working on database security & privacy supervised by Prof. Xi He, as part of the Data System Group (DSG). I am looking for research internships in 2023.

My research interests mainly lie in the field of computer security & data privacy, as well as its intersections with database systems and machine learning. I am excited to apply formal security and privacy analysis and develop solutions that are both theoretically sound and practically feasible. I have previously worked on machine learning robustness, access control privacy, location privacy, differentially private data synthesis, secure protocols (e.g. data sharing and e-voting), with a recent focus on the security&privacy problems in database systems. I am so fortunate to work with many nice professors and talented colleagues. Our research results have appeared on conferences ITCS, VLDB, IEEE ICDCS, TPDP, and journals IEEE TVT, and Int. J. Inf. Secur.
