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.
Research
I study the syntax and semantics of type theory and programming
languages, through an algebraic lens. I am particularly interested in the
semantics of syntax, applying categorical techniques such as
gluing to obtain abstract normalization results.
My colleagues and I have developed the
redtt proof assistant
for Cartesian cubical type theory.
