Academic Background

I am a Research Systems Scientist at CyLab at Carnegie Mellon University.

My research focuses on usable security, trust management, and network security.  I also work on security for Vehicular Ad-hoc Networks (VANETs), wireless networks, and home networks.

I received my B.A. in Computer Science from University of California, Berkeley, my M.S. in Computer Science from Yale University, and my Ph.D. in Electrical and Computer Engineering from Carnegie Mellon University.
