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. this one on diameter of reconfiguration graphs 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).
