About me

I am a CNRS junior research scientist in mathematics, working at ENS Paris. I am currently interested in nonlinear control theory, fluid mechanics and boundary layers.

I wrote my PhD thesis under the supervision of Jean-Michel Coron on control in fluid mechanics, defended in September 2016. I was then a post-doc student of Anne-Laure Dalibard and Karine Beauchard. I worked for 5 years at IRMAR laboratory, in Rennes, France.

Dear editors, due to my personal conviction for open science and an always increasing number of review demands, I will prioritize reviewing papers for diamond open-access journals starting January 2022.
