Professor of Financial Economics, Radboud University, Nijmegen, The Netherlands and Associate Professor for Fintech - Experimental Finance, University of Zurich, Switzerland

Why do individuals, even financial professionals, often make sub-optimal financial decisions? And what can we do about it?

A large part of the answer can be found in psychology. I conduct fundamental as well as practically relevant research in investor psychology ("behavioral finance") and use my insights to consult banks and insurance companies improving their products and services. Primarily, I develop and implement innovative methods to measure and assess the risk preferences of investors (“risk profiling”), taking into account the ongoing digitization in the financial industry (FinTech). My research aims understanding investor psychology and supporting them making better decisions. I am affiliated with the Swiss FinTech Innovation Lab. Further, I am Treasurer, Managing Board Member and Scientific Board Member Society for Experimental Finance and Associate with BhFS Behavioural Finance Solutions, Zurich, Switzerland.
