I'm a math professor at Northwestern university. Here's a picture of me. Here's a picture of a glacier while I'm standing near it.Mostly I'm interested in symplectic topology, which is a field of math related to holomorphic geometry, smooth topology, and mathematical physics. In practice this means I spend a lot of time trying to imagine complicated 6 dimensional shapes, how to break them into small pieces, how these building blocks fit together, and what that tells us about the architecture of these spaces. Maybe this is an effective way to think about string theory and understand the true nature of the universe. I don't really know, mostly I approach my work from a sort of aesthetic perspective.
