About

I am a doctoral candidate at Indiana University Bloomington, advised by Amr Sabry. I'm currently a visitor at the Computer Laboratory, University of Cambridge.

Research

I study type theories and programming languages, through the lens of category theory. I'm also interested in mathematical logic, constructive mathematics, and formalization.
