Hi! My name is Wojtek (voy-tech, like in envoy and techno). Currently, I am a PhD student in the Department of Philosophy at Carnegie Mellon University supervised by Jeremy Avigad. My research is in interactive and automated theorem proving, programming languages, type theory, and mathematical logic. I am also a developer of the Lean 4 theorem prover. I have a long-time hobbyist interest in cryptography. This is my personal website. Check out my publications, posts, and writeups of CTF (a kind of cybersecurity competition) challenges.
