I am a junior CNRS researcher affiliated with the team MMCS (Mathematical Modelling and Scientific Computing) at Institut Camille Jordan (UMR 5208) at Université Claude Bernard Lyon-1.
Full CV (PDF format): English version/French version.
My mathematical self currently leans toward reaction–diffusion partial differential equations and systems and mathematical models for population biology (ecology, evolution, epidemiology, population genetics). In particular, I am interested in long-time qualitative behaviors: persistence, extinction and especially propagation phenomena (asymptotic spreading, traveling wave solutions and generalizations of these notions).
Secondary focuses worth mentioning are principal eigenvalues of parabolic and elliptic operators, non-local parabolic and elliptic PDEs, free boundary problems, singular limits and mathematical models for social sciences.
On the biological side, I have studied models of competitive displacement, territorial expansion, evolution of dispersal and spatial sorting in expanding ranges, evolution of Allee effect, populations structured both in space and age, CRISPR-Cas9 gene drive.
I was the lead organizer of an interdisciplinary PDE–biology workshop in Orsay (France) on November 25th and 26th, 2019, thanks to a funding of the Fondation Mathématique Jacques Hadamard.
I was co-organizer of the SIMBAD biomathematics seminar and lead organizer of its first meeting (May 24th, 2016, LJLL, Paris).
My PhD thesis was entitled Propagation phenomena and reaction–diffusion systems for population dynamics in homogeneous or periodic media and supervised by Grégoire Nadin and Vincent Calvez. You can find the manuscript here.
On two-species competition--diffusion Lotka-Volterra systems
On non-cooperative Fisher--KPP systems
On gene drive reaction--diffusion models
The slides of any talk I gave in the past are available on demand (simply email me).
During my PhD, I was tutoring (“Chargé de Mission d’Enseignement” in French) at UPMC, assigned to multivariable calculus courses (“UE 2M216” and “UE 2M256”).
An interview of me (in French) by the CNRS.
My ORCID profile (0000-0001-8201-2053).
I am among the Nonlinearity Outstanding Reviewers of 2018 and I am an IOP Publishing Trusted Reviewer.
I have a master degree in epistemology. The science studies, in its most general sense, still interest me strongly. I am inclined to discuss with anyone and to learn more about, for instance, the sociology of mathematics (a reference (in French)) or the history of population dynamics (a reference).
A fancier website will replace this austere page. Someday. (At least, web accessibility is not an issue here.)
During my free time, I practice and teach aikibudo (black belt 3rd dan).
