I am an Associate Professor in the School of Computing and Information at the University of Pittsburgh. My research broadly spans the areas of Distributed Systems and Data Privacy. At Pitt, I co-direct research in the Laboratory for Education and Research on Security Assured Information Systems (LERSAIS). I am also an Affiliate Scholar at the Institute for Cyber Law, Policy, and Security. Prior to joining the University of Pittsburgh, I received my Ph. D. degree in Computer Science from Georgia Institute of Technology.
PhD positions: We’re always looking for
self-motivated and dedicated Ph.D students. If you
are interested in joining our research group, please apply to
our graduate program.

RESEARCH:
My research interest lies in the areas of Data Privacy, Privacy-aware Computing, Distributed Computer Systems and Cloud Computing. I am especially interested in tackling problems related to scalable and privacy-conscious computing and data sharing in untrusted and outsourced computing environments.
