Biography
Sophie Violette
Hydrogeologist – Research items
• Characterization of aquifers/aquitards: geometry and hydrodynamic properties
• Past evolution of hydro-systems for the understanding of their dynamics in the present, and even in the future: transient evolution of medium and long term hydro-systems following climatic, geomorphological, tectonic and anthropic forcings
• Study of the processes of recharge/evapotranspiration of shallow unconfined hydro-systems and quantification
Sophie Violette has joined the Ecole Normale Supérieure (Laboratoire de Géologie) for her research activity in 2014. She received a PhD (1993) then a HDR (2003) on Hydrogeology from the University of Pierre et Marie CURIE (UPMC, now Sorbonne University). She is Assistant Professor in Hydrogeology at the UPMC since 1995, and was doing her research at Laboratoire de Géologie Appliquée, then UMR.7619-Sisyphe. She was invited as visitor scientist at John Hopkins University, team of Pr. Grant Garven (1999) then at Stanford University, team of Pr. Steve Gorelick (2005). Since 2019 Sophie Violette is Assistant Director of UMR.8538-Laboratoire de Géologie ENS (PSL University Paris).
The main goal of her research activities is the understanding of groundwater flow at various spatial and time scales (watershed to sedimentary basins and daily to 106 years, respectively) by identification of: 3D geometry (from geological and geophysical data), properties and physical processes involved (mechanical, hydrodynamic, heat and solute transfers) and boundary conditions (Natural forcings: Tectonic, eustatism, climate and; Anthropogenic forcing: Pumping). Her scientific activity includes a large proportion of groundwater flow modelling constrained by: geological, geochemical, isotopic or thermal data. She has a multidisciplinary background and a field experience performed in developed and developing regions submitted to various climates: France (volcanic islands and sedimentary basins), Bulgaria and Madagascar (bedrocks), India (sedimentary basin), Ecuador, Indonesia, Iceland and Lesser Antilles (basaltic and andesitic volcanoes). Her expertise is strengthened by a strong experience for collaborative research and coordination of research projects with national and international collaborators. Her research is funded by: public organisms (AESN, ANDRA, ANR, ANRT, Campus France PHC, CEA, Chancellery of Universities, CRIF, INSU, IRSN, SEDIF), private companies (DANONE, EDF, ESA, GdF-Suez), Enterprise Foundations (Ensemble, Foundation of France, Schlumberger, Véolia) or International organisms (PNUD, World bank). She has been serving as expert on hydrogeology for a number of national committees (ANDRA-COS, IFPEn-CS, Universities-CSE, INRA-CSS) and reviewer for journals and funding agencies, national and international.
