Short description

My research concentrates on special functions, and in particular on q-special functions, and their relationship to other mathematical structures like (Lie) groups, (dynamical) quantum groups, Hecke algebras, and non-commutative geometry. At the moment the special functions are one-variable basic hypergeometric series like Askey-Wilson polynomials, q-Racah polynomials and their subclasses, as well as q-analogues of the Bessel function, and Askey-Wilson functions. Tools that are being used are representation theory, spectral analysis, operator algebras.
