I try to entertain people with talks on interesting problems and improve this.

Some talks of mine are recorded and made publicly on YouTube, e.g. on diameter of reconfiguration graphs, Erdos-Nesetril and one on the 69-conjecture and independent sets.

Collaborations are an important tool to make progress on harder questions, by combining expertises.
As such, I like to be part of such collaborations, both during physical and online events such as organised by the sparse graph coalition.

I am also involved with the training of the Flemish high school talents, and I proposed problems at different olympiads, e.g. IMO 2020 question 2 and IMO 2022 question 5 (composed together with Tijs Buggenhout).
