I am a PhD student since October 2018 under the supervision of Dasha Loukianova (Université d'Évry, LaMME) and Eva Löcherbach (Université Paris 1, SAMM). My thesis is dedicated to the study of large scale limit of (stochastic) particle systems in a diffusive regime, and particularly for systems with Hawkes-type dynamics. I am more generally interested in applications of mathematics and computer science to model biological phenomena.

• Interacting particle systems, nonlinear multivariate Hawkes processes, mean field limits, propagation of chaos
• Point processes, Poisson measures
