About me

I am a postdoctoral researcher at the Laboratoire de Mathématiques d'Orsay in the group of Nicolas Curien. I am funded by the ERC SuPerGRandMa and organise the weekly SuPerGRandMa seminar in Orsay.

Prior to this, I was a PhD student at the ENS de Lyon, under the supervision of Grégory Miermont. The manuscript of my thesis can be found here.

Research interests

Random trees, random maps, and their scaling limits. Stochastic processes. Log-concavity and total positivity. Probabilistic couplings.
