I’m a full professor in Industrial Organization at the Faculty of Economics and BusinessUniversity of Groningen, the Netherlands.

I’m also the program director of the MSc Economics.

My research interests are primarily in the field of Industrial Organization. I’m doing mostly theory, but also run experiments and have done some empirical things.
