Reaching out

Changing Photo

Reaching out, communicating and sharing what it is we do to non-specialists, is vital, important and rewarding. I spend a lot of time working on outreach projects of different types, including creating exhibits for science festivals, games, and exploring the relationship between creativity and mathematics. This greatly influences how I share math, including in more traditional formats like in seminars or classes.

I've been lucky to work with many wonderful outreachers, mathematicians, artists, designers and computer scientists. In terms of both creation of activities and event organization, my main collaborator is Bruno Teheux from the University of Luxembourg.

In terms of content creation, Paul Turner (University of Geneva), Mario Guttiérez and Reyna Juárez are precious collaborators. Ann Kiefer (University of Luxembourg), Laurent Loosveldt (University of Liège), Marie Abadie (University of Luxembourg) and Bruno Dular (University of Luxembourg) are all talented mathematical outreachers that have helped share our activities in various venues. There are too many past events to list here, but we've truly been around the world with these projects.

We showcase mathematical games and art activities in science festivals and at general public venues including the Universal Expo and the Game On festival. In July 2025, we were at the Universal Expo in Osaka on three pavilions (Luxembourg, Belgium and Switzerland).

I was curator and contributor for the Shapes exhibition at the EPFL, in between mathematics and art. It featured some of our projects created with Bruno, Paul, Mario and Reyna.

Bruno Teheux and I launched the Girls Exploring Math initiative which we co-organize together with Ann Kiefer.

Together with Bruno Teheux, we created the ReShape project (part of Sound of Data for Esch 2022). We collected over 20000 drawings and gave them to three musicians who composed music based on them: Music by Hester 1, Music by Mike von der Nahmer and Music by Timelord.

My first major outreach project was the Mathema project created together with Paul Turner.

Games

Quadratis is a joy packed exploration game created together with Paul Turner and Mario Guttiérez. Download it (available on the App Store and on Google Play).
Exploratis, based on Quadratis, allows visitors to visualize their game strategies and compete against each other. It has been installed at the Science Center in Differdange and at the Sciencescope at the University of Geneva.
With Bruno Teheux, we created the games Involution, Revolution and Cyclicity.
