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 Publications Sharing Private Data Over Public Networks, Randy Baden Ph.D. Thesis, 2012.

(PDF) 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. PeerWise We exploit Triangle Inequality Violations to find faster paths to destinations in the Internet. More I have interests beyond academia as well.
