Activities

FD Seminar

I am one for the organisers of the FD Seminar, an online seminar on representation theory of quivers and finite-dimensional algebras.

FDLIST

Since May 2021, I am one for the maintainers of the FDLIST, an information list that provides a forum for the exchange of information, ideas, problems and questions, which are related to representation theory of finite-dimensional algebras.

Network on Silting Theory

I am a member of the Network on Silting Theory, which is funded by the Deutsche Forschungsgemeinschaft, DFG.

Learning seminar

Together with Bernhard Keller (Université Paris Cité) I organise an online Learning Seminar on Higher Category Theory and its Applications to Algebra and Geometry. At the moment this is private seminar; if you are interested in participating please contact either Bernhard or myself by e-mail.
