CV

 

I am an Assistant Professor in the School of Computing and Information in 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). 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.
