I'm a postdoctoral fellow in the
Computational
Mathematics division
at Stockholm University, hosted by Anders Mörtberg. Previously, I was a Ph.D. student in
computer science at Carnegie Mellon
University under Robert Harper.
I study constructive type theories, particularly new ways to treat proofs asconstructions. My
current research focuses on the constructive reading of equality proofs as paths in a space, which is
the basis of cubical type theories. I am developing features we can build into these theories
(such as higher inductive types and internal parametricity), exploring their applications
(such as for representation independence), and working to systematize the design of cubical
type theories.
