About Me

I am an Associate Professor in the School of Computer Science at McGill University. I am a theoretical computer scientist, which means that I use mathematical tools to study the nature of computational processes. My main research topic is computational complexity theory, although I am particular interested in the intersection of complexity and mathematical logic, through proof complexity and related topics. In SOCS, I run the Complexity Lab with Hamed Hatami.

You can look at my curriculum vitae for more of my (professional) past life, if you’re into that sort of thing. Otherwise, scroll on down to find my research papers, my graduate students, or my recent teaching.

Sabbatical, 2026–2027

beast on my brain, every thought is the same
if the beast is controlled, it’ll never turn gold
and that’s just fine
we don’t own the world around us
