Ponsin, Violaine

My research interests lie in the fate of organic contaminants in groundwater. I am currently involved in two research projects, one focusing on pesticides and the second one on petroleum hydrocarbons. Both projects apply Compound-Specific Isotope Analysis to assess processes responsible for the degradation of these organic contaminants in groundwater.

Education and Positions held

2014-Present : Postdoc at the Centre for Hydrogeology and Geothermics (CHYN), University of Neuchâtel, Switzerland, in group Hydrochemistry and Contaminants

2011-2014 : PhD student at the Laboratory for Environmental Chemistry (LCE), Aix-Marseille University, France, in group “Développements Métrologiques et Chimie des Milieux”

2007-2011 : MSc of Environmental Sciences, AgroParisTech, France
