I'm a Golomb Visiting Assistant Professor at Purdue. Next fall, I'll be a visiting assistant professor at Texas A&M University. I work on the intersection of stable homotopy theory and number theory.

My CV.

I study chromatic stable homotopy theory from the point of view of the geometry of formal groups and p-divisible groups. I'm particularly interested in transchromatic questions: what happens when formal groups change height, and what this tells us about chromatic localizations. I'm also interested in using the analytic geometry of Lubin-Tate space to study the action of the Morava stabilizer group.

I made a short video summary of my current research for the electronic Algebraic Topology Employment Network. You can watch it on Youtube.
