Research in Progress
On the Demand for Mental Models (with Katharina Momsen)

Publications
Don't Put All Your Legs in One Basket - Theory and Evidence on Coopetition in Road Cycling (with David Piazolo)
European Economic Review: Volume 170 (2024)
- Theoretical and empirical analysis: How do characteristics of riders in competing groups of cyclists impact cooperation within these groups?
- Main Takeaways: Having a teammate in a competing group creates free-riding opportunities (in both groups). Asymmetric groups tend to cooperate better.
- Applications in IO, e.g. coopetition in ports or tourism destinations.
Finding Large Rainbow Trees in Colorings of 
The Electronic Journal of Combinatorics: Volume 30, Issue 4 (2023)
- Pure Mathematics (combinatorics).
- I prove that asymptotically, the bipartite graph with 2n vertices (see picture for n=5) can be partitioned into n copies of any tree with n edges.
