Vincent Lagneau is the Deputy Director of Mines ParisTech's Center of Geosciences. He holds and engineering degree from Ecole Polytechnique, a PhD from Mines ParisTech and a HDR in Geosciences. His research themes deal with understanding and quantifying water-gas-rock interfaces in porous media. He coordinates and actively participates in the development of the code HYTEC, which couples the description of transfer mechanisms (water and dissolved elements, gas, heat) with geochemical reactions. The simulations and developments explore the relationships that can modify the behavior of these highly coupled and non-linear systems.
