Research Interests

I am primarily interested in designing protocols to enable computing on encrypted data. In particular, I am interested in understanding how can we store, search, compute, and collaborate with others without compromising the privacy of our sensitive data. My research concerns both the foundational questions of when such constructions are possible as well as the application-motivated questions of scaling these techniques for real-world applications.

I am always looking for motivated students. Please email me if you are interested.

About Me

Prior to joing GW, I was a research scientist in the Secure Resilient Systems and Technology Group at MIT Lincoln Laboratory where I worked on applying tools from theoretical cryptography to practical applications for the US government. Prior to that, I received my PhD under Jonathan Katz in the Computer Science department at the University of Maryland. My PhD thesis studied the limitations of blackbox and non-blackbox cryptographic constructions.
