I work on building theoretically sound and practically efficient cryptographic protocols that address—in the broadest sense—the dual concerns of privacy and accountability. To that end, the main focus of my research thus far has been on such objects as blind signature schemes, authentication schemes and zero-knowledge proof systems (among others) with a particular interest in (classical) pairing- and (post-quantum) lattice-based cryptography.
I am also interested in algebraic geometry, specifically the arithmetic of elliptic curves.
