Research Interests

• Representation theory of finite-dimensional algebras and quivers
• Geometry of module varieties and quiver Grassmannians
• Cluster algebras and their categorifications
• Preprojective algebras
• Biserial algebras
• Kac-Moody Lie algebras and quantum groups (e.g. geometric realizations of crystal graphs, and semicanonical bases)

Teaching

• WS 21/22
• SS 22
• Master and PhD students

Master students who intend to continue with a PhD in Representation Theory should regularly attend research seminars (like the online FD-Seminar and the Paris Algebra Seminar (Keller)).
