I am a PhD candidate in the area of cryptography, working under the supervision of Dr Jens Groth and Dr Sarah Meiklejohn. I am currently working on efficient zero-knowledge proofs. More specifically, I am looking at zero-knowledge membership proofs. I am also interested in lattices and post-quantum cryptography, game theory, and both classical and quantum information theory.

Before coming to UCL, I studied Mathematics to Part III at Clare College, University of Cambridge.

I help to organise UCL's ACE-CSR and Information Security Seminars. Please don't hesitate to get in touch if you would like to get more information or join our mailing list.
