Mathematical interests
- Modular representation theory of finite groups
- Intersections between representation theory and tensor-triangular geometry
- Non/commutative tensor-triangular geometry
- Invertible objects/Picard groups
- Permutation modules
- Tensor categories, oligomorphic groups
Here is an informal summary (for experts in the field) of things I’m currently thinking about as of February 2026.
In preparation / Ongoing projects
- Permutation twisted cohomology (the finite groups remix, Noetherianity(!!)) (w/ J. O. Gómez)
- The tensor-triangular geometry of tensor categories (w/ T. De Deyn)
- The tensor-triangular geometry of some oligomorphic groups (possibly multiple projects or merged with above, w/ N. Harman, maybe more)
- Local Picard groups for permutation modules
- Noncommutative tensor-triangular geometry of $p$-group algebras (w/ K. Vashaw)
- Something with central triangulated subcategories (in the sense of Krause)
