I received my BSc from HKUST in 2010 and my MMath and PhD from the University of Waterloo in 2012 and 2016 respectively. I was an Assistant Professor at the Hong Kong University of Science and Technology between 2016 and 2020. I've served on the Program Committee of the Privacy Enhancing Symposium from 2017 to 2020.
My research is in privacy-enhancing technologies, with a special focus on anonymity networks. I proposed congestion-detection mechanisms to speed up Tor circuits and various preloading strategies to reduce load times on Tor Browser. I am analyzing Website Fingerprinting attacks that can potentially compromise Tor; I have previously published new and more powerful attacks as well as stronger defenses to defeat those attacks, especially in realistic low base rate scenarios. I am currently investigating real-world implementations of these algorithms and limitations in the analysis of defenses.
Recently, I published at IEEE S&P 2020, NDSS 2020, and USENIX 2020 (with my student, Jiajun Gong).
PhD Thesis: "Website Fingerprinting: Attacks and Defenses"
Papers/data/code for my research can be found here.
I created and taught a Principles of Cybersecurity undergraduate-level course at HKUST for several years. I am currently creating an Information Privacy course for the Cybersecurity Master's cohort at SFU.
