I have been an Associate Prof. of Quantitative Hydrogeology at UR1 since september 2006.
You can read more about my background here.

I am currently in charge of research team TERA ("Fluids, Transport and Reactivity"), after having been for Background years in charge of team DIMENV ("Dynamics, Imaging and Modeling of Environmental Systems") and for 4 years in charge of the Hydrology group within DIMENV. See here the presentation (pdf) of the team's activity for the period 2016-2020, which I prepared and gave at the occasion of the HCÉRES audit of Géosciences Rennes in March 2021.

I have also been in charge for some years of the Analog Lab for Experiments in Hydrology, which in 2022 was included into the new OSU platform IMAGEO for experimental imaging of hydro-bio-geophysical systems. See here the presentation (pdf) of the lab's activity for the period 2016-2020, which I prepared and gave for the aforementioned audit (it is also available as a video on youtube here).

My scientific interests include the couplings between flow (including two-phase flow and the flow of non-Newtonian fluids), solute mixing and transport (including reactive), and biological activity, in porous and fractured media, as well as the physics of clay minerals (swelling, water diffusion, complex fluids made of clay suspensions). Applicative contexts include soil remediation and underground storage of CO2. I combine laboratory experiments (table-top setups and synchrotron experiments), numerical simulations and theoretical analyses (when possible). My research page will tell you a bit more.
My publications are listed here.

Over the years I have taught various aspects of transfers in the subsurface, and of catchment hydrology (including hydrological risks). Between September 2008 and August 2012 I was responsible for the environmental course of the Master program "Systèmes Complexes Naturels et Industriels" of Université Rennes 1.
