About Me

I’m a postdoctoral researcher in the Department of Mathematical Sciences at the University of Copenhagen. I completed my PhD at UCLA under the supervision of Paul Balmer.

Research Interests

Triangulated categories and their applications, especially tensor triangular geometry and examples arising in stable homotopy theory, modular representation theory, algebraic geometry, and noncommutative topology. Other interests include equivariant homotopy theory, motivic homotopy theory, higher category theory, and the representation theory of groups and associative algebras.
