Current courses
In Winter 2026/27, I'm teaching organizing a Graduate Seminar on modular forms and elliptic curves. Please let me know if you'd like to access the Sciebo folder with details and talk notes.
I'm also an Assistant for Tasho Kaletha's course on Algebraic Groups. While eCampus is down, here is Sheet 2.
This is the splitting field of x^7 - 41, pictured using Havard Damm-Johnsen's software drawspec.
See the notes from my Algebraic Number Theory course to learn what it means!
Summer research
In Summer 2025 (together with Andrew Graham) I supervised an undergraduate research project for Pedro Lack and Zhiyi Luo.
We're currently finishing the resulting paper on Beilinson's conjecture for universal families of elliptic curves.
