I am a Faculty Fellow / Assistant Professor at New York University, hosted by Marshall Ball and Yevgeniy Dodis.

My research focuses on exploring the space-constrained aspects of cryptography, including but not limited to the Bounded Storage Model, incompressible cryptography, space lower bounds, etc., though I am broadly interested in other topics in cryptography and theoretical computer science in general.

I earned my PhD from Princeton University, where I was fortunate to be advised by Mark Zhandry. I graduated with a B.S. with Honors and a M.S. from Stanford University, with Dan Boneh as my advisor.

When I’m not working, I mostly enjoy photography, theater, and cooking.
