Biography

I am a Hadamard Lecturer at CMAP (Ecole Polytechnique) under the supervision of Giovanni Conforti, (CMAP,X). Before that, I was doing a PhD under the supervision of Nicolas Fournier, (LPSM,SU). Here is my CV and you can find my thesis here

My PhD thesis is about the study of the collisions of the Keller-Segel model in the supercritical case in both determinsitic and stochastic cases. My current postdoc project is around large deviation of the branching Bronwnian motion.
