Xavier Erny

Xavier Erny is an Assistant Professor at Télécom SudParis, part of Institut Polytechnique de Paris and Institut Mines-Télécom since October 2023. He holds a PhD in Mathematics from Université d’Evry (2018-2021), supervised by Dasha Loukianova and Eva Löcherbach, focusing on large-scale limits of stochastic particle systems. Before his current position, he was a postdoctoral researcher at École Polytechnique (2021-2023), studying invasion phenomena in population dynamics. His research interests span stochastic analysis, interacting particle systems, and large-scale limits, with a focus on Hawkes processes, McKean-Vlasov equations, and neural network modeling.

• Education:
• PhD in Mathematics, Université d’Evry (2018-2021)
• MSc in Mathematics, Sorbonne Université (2018)
• BSc in Mathematics/Computer Science, Ecole Normale Supérieure Paris-Saclay (2015-2017)

Research Interests: His work centers on stochastic differential equations, mean-field limits, and applications to neuroscience and population dynamics. Recent studies include diffusive scaling of interacting systems, propagation of chaos, and annealed limits for disordered models.

Teaching: Currently teaches Probability and Statistics (MAT8453) at Télécom SudParis, and has prior experience in probability courses at Université d’Evry and Ecole Polytechnique.
