I work at the Laboratoire de mathématiques d’Orsay, and Faculté des sciences d’Orsay, part of Université Paris-Saclay.

My research is focused on

• geometry, group actions, dynamical systems
• translation surfaces and their moduli spaces

I have a strong interest in

• free software for mathematics and science, in particular SageMath
• mathematical illustration, see projects at Illustrating mathematics
• reproducible research

I took part in the OpenDreamKit project, 2015–2019.
