Jason Schoeters


I am currently a research associate at the Faculty of Economics of the university of Cambridge working with Peter Bossaerts.

My main research interests are temporal graph theory, swarm intelligence, and optimization.
I also enjoy the occasional coding project and learning about new subjects.

Experience

Research associate

With Peter Bossaerts, we aim to better understand the correlations and/or differences between human brains and computers artificial intelligence when faced with complex problems. One goal is to find and characterize problems where humans have the advantage, such as when intuition, context, and/or pattern recognition plays a key role.

2023 - 2026

Postdoctoral research fellow

With Eric Sanlaville, we have mainly studied connected components in temporal graphs, presenting numerous temporal extensions and corresponding structural and algorithmic results, which were either novel or which completed related work. A secondary subject considered dense spanners in temporal graphs, for which we obtained preliminary results.

2021 - 2022

Research and teaching assistant

A year mainly filled with teaching. I tied up some loose ends from my PhD and started new projects by myself or with new people. I also took some time to broaden my horizons and even obtaining results in other domains, including learning about probability theory with Luis Fredes and bioinformatics with Clément Larue.

Software development

All my coding projects, from experimental benchmarks for my own research subjects to automatic data processing for colleagues in biology. I mostly code in Java, due to my visualisation library of choice being JBotSim, although I prefer Python for small projects.

Students

All the students I have (co-)supervised which at the moment consists of internships only. As a rule, I prefer to work with my students as colleagues, not just teach them and review their findings.

Teaching

Following is a list of the classes I have given over the years, currently totalling at more or less 350 hours.

To my students, I like to keep useful links here (recordings, test/answer sheets, ...) for this year's classes.
As is the case with everyone, teachers can forget; contact me via jason.schoeters.cs@gmail.com if something is missing.

Bordeaux highschools

I was part of Maths à modeler in 2018, and of Math en jeans in 2019. Both aim to present some higher level maths (proper proofs, lower/upper bounds, divide and conquer, etc.) at highschools under the guise of an interesting and fun problem. For Maths à modeler, the students are generally guided along several weeks towards the solution(s) and props such as boards, tokens and tiles are often used to offer hands-on learning. Math en jeans leaves more room for the students to advance at the pace they like and in the direction they deem interesting. Both ultimately end with students presenting their findings at a seminar.

Free time

In my free time I like to meet with friends to have a drink or do an activity.
When it is rainy however, I like to read, or play (card, board, video) games with friends.
Concerning sports, I'm particularly fond of bouldering, and I like dancing, running, and hiking.
