About Me

I am a fifth year PhD candidate in Computer Science at the University of Michigan where I am working with Prof. Roya Ensafi. My research interests are digital security and privacy. I employ a mix of network and Internet measurement techniques to perform data-driven studies to analyze systems from security and privacy perspectives.

I am currently working my project: VPNalyzer, an academic research project that aims to analyze the VPN ecosystem through large-scale data-driven studies. VPNalyzer served as the first in a line of systematic investigations to evaluate popular VPNs at Consumer Reports! 🎉

I interned at Brave Research in summer of 2022!
