Teaching
Here is a link to the graph of my courses on probabilities that I give in the master TSI. It covers basics of probabilities / estimation theory / information theory, and ends with exponential families. The aim of this course is to provide a solid ground on these topics, without entering the topics of sigma-algebras and measurability.
Here is a link to the software used to creat the graph from a latex document.

Bio
Since October 2018 I am an assistant professor at Aix-Marseille university (AMU), in the "physics and image processing" team of the Fresnel institute. My research is focused on data science problems involving particular geometric structures. More precisely, I have been interested / work on:
- density estimation
- on manifolds (symmetric spaces and Lie groups)
- in deterministic contexts (using the co-area formula)
- the geometry of the space of color derived from the MacAdam ellipses
- non-scalar mathematical morphology
- 3D shape processing and facial motions
Before joining AMU, I was a post-doc at Duke university with David Dunson and Jana Schaich Borg, a post-doc at the Weizmann institute with Ronen Basri, and a phd student at Ecole des Mines de Paris with Jesus Angulo.
