Research interests
I am a full professor in mathematics (chair Lie theory) at the
KdV Institute for Mathematics
(Universiteit van Amsterdam). My research interests are

Lie theory, in particular representation theory of
quantum groups and affine Hecke algebras,

Integrable systems,
in particular integrable quantum many body systems
and integrable lattice models,

Hypergeometric functions, in particular basic and elliptic
hypergeometric functions associated to root systems,
and their interrelations.
Teaching
Representation Theory seminar
I am running a representation theory seminar together with
Eric Opdam. For more information and the schedule please consult
the website of the seminar.
