I am an Associate Professor in the Department of Mathematics at CU Boulder. I received my PhD from Northwestern in 2013 under the direction of Paul Goerss. My main area of expertise is topology and, more specifically, stable homotopy theory. I also study interactions between homotopy theory and condensed matter physics.
