Research Focus

I graduated from the University of Maryland in May, 2012 with a Ph.D. in Computer Science. I study distributed and decentralized systems, with an emphasis on security and privacy in Online Social Networks (OSNs). I am currently on disability retirement and am mostly unable to continue doing research.

Academic Lineage

My Ph.D. advisor was Bobby Bhattacharjee, and I also worked extensively with Neil Spring

Projects

  • LoKI: Location-based PKI for Social Networks
We use the ubiquity of mobile devices to allow users to verify OSN identities post-hoc after real-world meetings.
  • Bond Breaker: Secure In-Band Public Key Exchange on Online Social Networks
We study whether users are able to identify each other in-band by relying on rich out-of-band information that is implicit in OSN links.
  • Persona: Privacy-Enabling aRchitecture for SOcial Networking Applications
We give users flexible privacy controls over their OSN data that even protect the contents of the data from the OSN itself.
  • GeoMAN: IP Geolocation on Metropolitan Area Networks
We geolocate IP addresses specifically in the context of a metropolitan area to get more precise results than in WAN geolocation.
We exploit Triangle Inequality Violations to find faster paths to destinations in the Internet.
