I am an Assistant Professor of Computer Science at Stanford University and Founder of Censys. My research brings a large-scale, empirical approach to the study of security, abuse, and misinformation on the Internet. I build systems to measure complex networked ecosystems, and I use the resulting perspective to understand online behavior, uncover weaknesses, architect more resilient protocols/platforms, and guide policy decisions.

Students and Teaching

I lead the Stanford Empirical Security Research Group where I advise several Ph.D. students and postdoctoral scholars: Liz Izhikevich, Gerry Wan, Kimberly Ruth, Hans Hanley, Catherine Han, and Deepak Kumar.

I teach CS155 Computer and Network Security (2019-2021), CS356 Topics in Systems and Network Security (2018-2021), and CS249i The Modern Internet (2021).
