**Specific interests in probability :** Brownian motion in dimension 2 to 4 (in particular
Brownian windings, stochastic Green' formula, Brownian motion interacting with random magnetic impurities, intersection measure),

Gaussian free field and log-correlated fields in general, Brownian loop soup, multiplicative chaoses, Yang-Mills field, SLE, SPDE

**Outside probability theory :** Mathematical physics (in particular related to fields theory),
Riemannian geometry (in particular geometric and stochastic expressions of topological invariants, e.g. Euler characteristics and analytic torsion, and measures on moduli spaces),
Rough path theory

I am currently a post-doc at the university of Warwick, supervised by Aleksandar Mijatović
(Although I am currently visiting Nathanael Berestycki at the university of Vienna until the end of 2023).
I was previously in post-doc supervised by
Jon Keating, after I finished my PhD in Paris (LPSM) supervised by Thierry Lévy.

My research is mostly about the winding function associated with a planar Brownian motion, which can be seen as a sort of log-correlated field.
My initial motivation comes from relations with Yang-Mills field,
and in particular with the goal of defining in the continuum the measure associated with a GFF interacting with a Yang-Mills field.
Here is a self-contained short presentation of my work (dated from May 2021).

Here is a picture I made about Brownian windings,to depicte there fractal structure. |
