Bio

I am a fourth year PhD student at Cornell and Cornell Tech working on distributed algorithms and cryptography, co-advised by Rafael Pass and Elaine Shi.

Previously, I spent time as an engineer at Algorand implementing and testing consensus protocols, and before that I did my B.S. and M.Eng at MIT.
