I have been working on transfer modeling of contaminants in river water systems for 16 years. My research has been focused on the development of models that describe the biophysical interactions between the flows and the biology and chemistry of the biogenic elements and contaminants in rivers by integrating the interface zones and buffer zones between the surface water and the river beds from the scale of the processes to the scale of the watershed. I was awarded the Crystal Medal of CNRS (2013) for creativity, technical expertise and innovation, contributing to the advancement of knowledge and excellence of French research as well as the Novelization (2013), Best SWAT 2013 and 2018 Team Awards and International Environmental Modelling and Software Society Award (2018).
