I am a doctoral student of Robert Harper at Carnegie Mellon University studying type theory, programming languages and semantics. Previously I received a B.A. in Linguistics from U.C. Berkeley. My other interests include category theory, topos theory, formalization of mathematics, Assyriology, and ancient languages and literature.
I study the syntax and semantics of type theory and programming languages through the lens of categorical algebra, with an aim toward building better interactive proof assistants.
My colleagues and I have developed the redtt proof assistant for Cartesian cubical type theory.
