After attending law schools in Munich and Freiburg and a period in the publishing industry, the former business consultant joined Ketterer Kunst as business administration manager in 2006 and became managing director in 2017. The field of provenance research at Ketterer Kunst is a strong focal point of his activities.

For him this field of research offers great opportunities to visualize historic contexts and human fates.
