Research Interests

My interest is in finite and infinite groups and its actions.

• Groups and geometries
       For instance structure of finite groups; Kac-Moody Groups; Aut(F_n);
       reflection groups, Coxeter groups and generalisations (such as elliptic Weyl groups).

• Presentation of groups and the underlying combinatorics
       For instance Artin groups; in particular the dual approach to Coxeter and Artin groups
       as well as to elliptic Weyl groups; Hurwitz action; non-crossing partition posets and lattices.

• Permutation groups acting on finite or infinite sets
       For instance regular subgroups of primitve permtutaion groups.

• Group theory and applications:
       For instance permutation polytopes; Cryptography

Dual Coxeter Systems
