I've been working as a postdoc at the University of Heidelberg since October 2016, in Johannes Walcher's group at the Mathematisches Institut. Previously, I was a graduate student in particle physics at Caltech, under Sergei Gukov. As part of my duties here, I'm helping to organize the Über-Seminar „Physical Mathematics“, together with Richard Eager.
During graduate school, I was interested in a range of things which, depending on your perspective, could be described as fairly wide or unbelievably narrow. Most, at least loosely speaking, are mathematical aspects of quantum field theory. The list has included topological quantum field theory, knot homologies, moduli spaces, arithmetic geometry, real homotopy theory, and quantization, and has recently expanded to include discrete models of holography and a smattering of quantum information theory.
For a tour of some of these ideas, take a look at this introductory review I coauthored a surprising number of years ago now, which is written with a non-specialist audience in mind. Depending on your taste, you may also appreciate a similarly leisurely review of somewhat different terrain, written in the less distant past. There are also videos available of lectures I gave in summer 2015, discussing a story related to the first of these with an eye toward arithmetic. More about that should appear (I hope) sometime soon.
