Pierre Humbert

Postdoc in probability and statistics

 

Since September 2024, I am a postdoctoral researcher in the Laboratoire de Probabilités, Statistique et Modélisation (LPSM) at Sorbonne Université with Etienne Roquain. I am also a membre of the MARS project.

Prior to that, I was a postdoc in the probability and statistics team of the Laboratoire de Mathématiques d'Orsay (LMO) with Sylvain Arlot. I was also a member of the INRIA Celeste team. I completed a PhD at ENS Paris-Saclay in 2021 entitled Multivariate analysis with tensors and graphs - application to neuroscience, under the supervision of Nicolas Vayatis, Laurent Oudre, and Julien Audiffren.
