Open access of research is important to me and as such, all my papers are published on Arxiv.
Also reviewing is important, so the papers are (at some point) also submitted to refereed journals.

Below, one can find a selection of my own work.

These are directions in which I am still interested and I hope to make progress on these in the future as well. Next to that, I am looking to some more pure extremal graph theory and extremal set theory questions.

I do some reviewing myself, both in-depth reviews for journals as reviews for MathScinet and ZbMath. It is a good way to get in touch with some recent work and it is important that proofs are correctly verified.
In the past, as an anonymous reviewer I even helped a few times improving the paper by providing shorter/ more elegant proofs.
In 2023, I reviewed for the following journals;
Electronic Journal of Combinatorics (2*), Journal of Graph Theory (2*), Journal of Combinatorial Theory Series B (1*), Discrete Mathematics (1*); as well as for Eurocomb (conference).
I also had to refuse the request to review a few times, e.g. for Combinatorica.
