Thibault Candela
Functie:Geomechanics Scientist | Human-Induced Subsidence and SeismicityIn my role as lead scientist of the PMC Subsidence I ensure that our research development and project portfolio are aligned with social and market needs. One of the burning challenges we face is: how to identify the individual subsidence contribution of each of superimposed deep and shallow subsurface activities? The deployment of complementary ex situ and in situ monitoring strategies is key in this regard.
