About me

I am a fourth year PhD candidate in Computer Science at the University of Michigan where I am working with Prof. Roya Ensafi. My research focuses on areas where the privacy, security and availability implications of networked systems affect users in the real world. My interests include network security, Internet measurement, and censorship study.

Previously, I was a research intern at Cloudflare Research
