My current research interests are in developing theoretical
foundations for privacy in networked systems. Specifically, I
apply tools in statistical signal processing, information theory
and game-theory to study fundamental trade-offs between user
privacy and quality-of-service (QoS) in data networks under
different adversarial conditions. I am also interested in
studying information leakage in cyber physical systems including
the smart electricity grid, peer production and transportation
systems. I am
a recipient of the 2011 CAREER Award from the National Science Foundation and
was awarded a P. C. Rossin Assistant Professorship by the Rossin College of
Engineering and Applied Sciences (RCEAS) at Lehigh
University.
My doctoral research was in the area of wireless sensor
networks, specifically on distributed multiple access
communication and statistical inference in large networks. Two
publications that resulted from my doctoral research received
the 2005
Leonard G. Abraham Prize and a 2006 IEEE ICASSP Best
Student Paper Award.
