Since 2014, I am Professor of Statistics at the Université Libre de Bruxelles (ULB). I am mainly teaching Mathematical Statistics, Multivariate Statistics and Statistical Learning. My main research fields are directional statistics, high dimensional statistics and dimension reduction techniques. I have always been interested in nonparametric methods such as rank-based methods or more recently methods based on optimal transport. I am also interested in asymptotics in general.
