**Research Interests.** Finite Groups, Representation Theory,
Computer Algebra. In particular, I'm interested in

- the structure of finite Coxeter groups and their associated Iwahori-Hecke algebras,
- the Burnside ring of a finite group and its table of marks,
- finite transformation monoids and semigroups,
- and in computational aspects of finite group theory.
