Mécanique des roches – Circulation des fluides – Structure interne des zones de faille – Modifications des propriétés physico-chimiques des roches
Présentation
Mes travaux de recherche s’intéressent aux processus physiques et chimiques s’opérant lors de la circulation des fluides dans les roches et à leurs implications sur la mécanique des failles et des séismes. Mes activités de recherche combinent i) des analyses structurales de zones de failles sur le terrain, ii) des expériences en laboratoire afin de mesurer les propriétés physiques de roches et leurs évolutions au cours des réactions métamorphiques et iii) de la modélisation hydromécanique et chimique.
