About Me

I'm an assistant professor in the Mathematics Department at UC Santa Cruz. Previously, I was a postdoc at EPFL and at the University of Copenhagen. I completed my PhD at UCLA under the supervision of Paul Balmer. Here's my CV. I also have a Google Scholar profile.

Research Interests

Triangulated categories and their applications, especially tensor triangular geometry and examples arising in stable homotopy theory, modular representation theory, and algebraic geometry. Other interests include equivariant homotopy theory, motivic homotopy theory, higher category theory, and the representation theory of groups and associative algebras. For the most part, my work contributes to the development of prismatic algebra.

Those with an excess amount of time on their hands can watch my talk at Triangulated Categories and Applications (recorded for the ages on 23 June 2016 in beautiful Banff). Thrilling stuff.
