I am a first year student at the Graduate Center of the City University of New York, supervised by Professor Rosario Gennaro. I can be found at the CAISS Institute. I wrote my Masters thesis on Homomorphic Signature Schemes with Yevgeniy Dodis  and the incalculably important guidance  of Dario Fiore. I am primarily interested in Cryptography and more broadly in Theoretical Computer Science. In particular my work so far has focused on designing provably secure protocols. See my Resume or choose from the links on the right for more details.

 

CURRENTLY : I am spending Summer 2014 at Microsoft Research India with the Crypto and Complexity team.

EDUCATION : I received an MSCi degree from Imperial College London and a Masters from the Courant Institute of NYU, both in Mathematics.
