Since August 2020, I'm also a Professor 2 at NTNU in Trondheim, here is a link to my webpage at NTNU.
The focus of my research is on the representation theory of finite dimensional algebras. In particular, I'm interested in cohomology theories, homological algebra, and connections of representation theory with other areas of mathematics.
NEW We are organising the workshop Quivers, representation theory and physics from 7.-9. September 2022 in Cologne. The aim of the workshop is to bring together mathematicians and physicists around the theme of quivers and representations theory.
LAGOON: Longitudinal Algebra and Geometry Open ONline Seminar in collaboration and with the support of ICMS: Every Thursday 1-2pm UTC+1 (CET). Open to all! Click here for the programme and details on how to join.
This semester I'm teaching Homological Algebra. The lectures will be live online via Zoom while the exercise sessions will be in person. Please find more details as well as the course material on Illias. Office hours on Zoom, please email me.
NEW New project C7 'Algebras from Fukaya and Quantum Field Theories' as part of the SFB/TRR 191 'Symplectic Structures in Geometry, Algebra and Dynamics'.
