I am the academic director of Swiss Mathematical Olympiad since 2017, and an active member since 2013.
I represented Switzerland as a contestant at the MEMO 2012 and at the IMO 2013. I was team leader at the IMO four times (2016, 2017, 2018, 2020) and once at the MEMO in 2014. I was a coordinator at the EGMO 2017 and at the BxMO 2018.
My favourite Olympiad topic is algebra.
I organized the second edition of the Olympiade Francophone de Mathématiques in 2021 - an international competition to which about 100 students from 9 countries took part.
Two of my own problems used at international level:
Here are a bunch of notes I wrote for Olympiad training. These are available (as for now only) in french and german. Assorted exercices and other teaching material can be found here.

If you wonder what Math Olympiad are, read the following article (fr) (de) published in the Bulletin de la Société Suisse des Professeurs de Mathématiques et Physique. If you wonder how Olympiad mathematics differ from traditional school mathematics, have a look at this (fr) (de).
