Research Interests

My research aims to enable collaboration between distrusting parties. From sharing and searching over private data, to computing joint results over inputs provided by multiple parties, I aim to build provably secure protocols to enable these tasks to be done while preserving privacy. I am interested both in the foundational questions of what is possible at all and based on what cryptographic assumption as well as the application-motivated goals of making this technology practical for real-world applications.

About Me

I joined George Washington University in Fall 2018. Prior to that, 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 for practical applications. I received my PhD in August 2011 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.
