I am a fourth-year PhD student in theoretical computer science at Cornell University. I am advised Noah Stephens-Davidowitz. My research is centered around post-quantum cryptography and the mathematical structures that enable the construction post-quantum cryptosystems, namely lattices and error-correcting codes.

I completed my Bachelors of Science at the University of California, Santa Barbara. There, I was advised by Tevfik Bultan. Under his guidance, I used program verification techniques to study the problem of information leakage.
