Hi there!

It's Talha. I am a Postdoctoral Researcher at the Ruhr University in Bochum, working with Kevin Borgolte. My research interests lie at the intersection of network measurement and security.

I am a recent Ph.D. in Computer Science graduate from Northeastern University in Boston, where I spent many happy years advised by David Choffnes. I finished my undergrad at the National University of Sciences and Technology in Islamabad.

My approach to research is to build novel measurement techniques, and to shed light on unexplored aspects of web protocols use that may impact security. My Ph.D. research focused on the security issues that stem from the diversity in TLS implementations and deployments. In the past, my work has uncovered issues with TLS adoption on the web (e.g., content differences), in mobile devices (e.g., inconsistent certificate pinning policies), and, in IoT devices (e.g., stale CA root stores).
