Homepage of Mikko Korhonen

I am currently working as a postdoctoral researcher at the University of Manchester, funded by a SNSF fellowship.

Previously I was at the École Polytechnique Fédérale de Lausanne, where I obtained my PhD under the supervision of Donna Testerman.

My main research interests are in group theory and representation theory. I am especially interested in simple algebraic groups and their subgroup structure, representation theory, and various properties of unipotent elements.
