Fall 2026 Office Hours
Tuesday/Thursday 4:30pm-5:30pm, Catskill 141 (on Podium), or by appointment

My research interests revolve around security, privacy, and trust in computing environments. Check out my research page and publications for more specific topics. I received my PhD in Information Science from the University of Pittsburgh, and my Master’s and Bachelor’s in Computer Science/Engineering from Sharif University of Technology and Ferdowsi University, respectively.

Interested in security and privacy research? Take a look at the opportunities and open positions.
