Personal details

I am Emeritus Professor of Pure Mathematics at the University of Leicester.

Research

My research interests are in the representation theory of finite-dimensional algebras, particularly in studying Hochschild cohomology and the Ext algebra. This includes finiteness conditions, support varieties, and cohomology rings for specific classes of algebras including generalisations of Koszul algebras.
