Welcome at the Personal Page of Stijn Cambie

Currently I am employed as a mathematician (funded by FWO) within a computer science department, but there is no existential crisis as I can be considered as a problem-solver in all regards.

One may also judge based on my Academic Background.
I am a former PhD student of Ross Kang at Raboud University Nijmegen.
The title of my thesis is "Extremal aspects of distances and colourings in graphs" and one can find both a full version and a Short version of it.
The introductory talk has been done in Dutch and has been recorded; Lekenpraatje.
I have been employed as a postdoc before at Warwick University, UK and Ecopro at IBS, South-Korea.
Currently, supported by a FWO postdoctoral fellowship, I work in the ALGT group at KULAK, Belgium.
Here I also teach Analysis I and supervise master students.
My main interests and experience are in combinatorics (mostly graph theory), but I am also intruigued by e.g. number theory.
People interested to work together on related things in the future can always contact me.

Research

Most of the research papers of me and my coauthors are immediately available on Arxiv.
Regarding homepages of coauthors, see e.g. Wouter Cames van Batenburg and Jorik Jooken.
By the Belgian way of working, recent published papers are also made available as much as possible at Lirias.
Progress on some problems of Erdos, with different (subjective) success, can be found at erdosproblems.com.
I also reviewed for many journals myself (and did shortly as well for MathScinet and Zbmath).

Teaching activities

Before the current teaching of Analysis I, I already encouraged students to process some mathematics. I have taught exercise classes (Linear algebra, mathematics I and - II) in Leuven as a master student up to May 2017 and in Nijmegen as a PhD student from September 2017 until June 2020 for various courses. In 2021, I was a highschool teacher for a short time. For many years, I teach talented high school students at the training camps of VWO vzw, and I have done some tutoring.

Varia

I am involved with olympiades as well.
I proposed questions e.g. for IMO, IMSC, EGMO (EGMO 2024 Q6, joint with Pierre Haas), LIMO , BxMO and EMC (e.g. JEMC 2024 Q4). I am involved with the coordination of the training at the Flemish training camps for the maths olympiads and the selection. At the BxMO, I have been crew member, leader, PSC member and head of PSC, organisator and chief coordinator. For the EMC (https://emc.mnm.hr/), I am the local organisator in Belgium, and the only local organisator who has done so in every edition. I also had the opportunity to teach to some of the most brilliant young problem-solvers at the International Mathematics Summer Camp.
