Hi! I'm a postdoc at Université de Bretagne Occidentale, working with Ismaël Bailleul. I'm working in stochastic analysis. I did my PhD at University Paris-Dauphine, where my advisor was Paul Gassiat.
It is a sacred tradition of mathematicians to obfuscate their emails. Here is my email address:
lmadry < at > univ-brest <dot> fr
I also have an email address associated with CEREMADE in Dauphine, but this one will be probably desactivated soon enough, so please do not use it. I also have an email address from LPSM, which is going to be active until August 2026, which I sometimes check.
Research themes:
regularisation by noise : mostly zero noise limits and large time behaviour of singular SDEs
fractional Brownian motion and its applications
rough paths
