I'm a Ph.D. candidate in theoretical computer science at Boston University, under the excellent supervision of Ran Canetti. For the spring semester of 2023, I'm visiting the Simons Institute for the theory of computing at UC Berkeley, where I'll be a full time participant of the Meta Complexity program.
I research topics in the intersection of cryptography and computational learning theory.
More about my research.
I have additional interests in pseudo-randomness and (meta-)complexity theory, as well as security issues in machine learning.
