The main theme of my mathematical research is Computational Harmonic Analysis with a special focus on Mathematical Data Analysis and Image Processing. 

The research group is integrated into the NuHAG. 

I am Vice-Director of Studies at the Faculty of Mathematics and I am co-organizer of the bi-annual conference on Applied Harmonic Analysis in Strobl/Austria.
