My research interest is mathematical analysis. I specialise in Geometric Measure Theory, a branch of fundamental mathematics of which the paradigm is the Plateau problem. It consists in studying the geometrical complexity of soap films and soap bubbles, including those in infinite dimensional spaces.

I grew up in Brussels, Belgium. I am currently a Professor at Westlake University and Honorary Maître de Recherches at the F.N.R.S., Belgium. I keep happy memories from working at Université Paris Cité – Paris 7 ; University College London, England ; Université Paris-Sud in Orsay, France ; Rice University in Houston, Texas ; and Université catholique de Louvain, Belgium.
