Research Interest

I’m broadly interested in computer security and web privacy. My current research focuses on privacy-enhancing technologies. Nowadays, the popularity of online advertisements has made them an attractive vector for various types of abuses. I’m working on improving the effectiveness of adblocking by (i) measuring/analyzing the escalating arms race between adblockers and anti-adblockers through program analysis; (ii) making adblockers stealthy against anti-adblockers via browser modifications; and (iii) leveraging machine learning to better identify advertising- and tracking-related resources.

Recently, I’ve also started to explore adversarial machine learning (e.g. adversarial example, Generative Adversarial Network (GAN)), and their applications in security and privacy research.
