My research project is dealing with the general challenge of linking the macronutrients cycles (C, N, P) in landscape hydrology. The scientific question is to understand how the inter-dependant processes between Carbon, Nitrogen, and possibly Phosphorus, which are controlling the chemical quality of stream waters. Although dissolved organic matter is acknowledged as the dominant form of exported C to hydrosystems, its importance for N and P cycling has to be better evaluated, in relation with the fate of dissolved organic nitrogen. There is a need to quantify the changes of river capacity to retain and transform macronutrients with stoichiometry.
I studied Agricultural Sciences in Montpellier SupAgro (International Centre for Higher education, Montpellier, France) where I specialized in Water Management in Agriculture. During my PhD thesis from 2007 to 2010, I was hosted at Irstea (ex Cemagref) Montpellier, France. I was interested in understanding the effects of hydrodynamics and hydraulic conditions on the development and removal of benthic algae in open-channel networks. I carried out some observations campaigns and experiments in 2 real networks in the Mediterranean region (the Canal de Gignac and the Canal de Provence). I also developed different modelling approaches: an algal growth model which integrates the hydraulic factor effects, a model of the fixed and drift algae dynamics in response to hydraulic flushes, and a linear model in order to develop a control framework for turbidity during hydraulic flushes. Then, I was recruited as permanent researcher in Water Sciences at French National Institute for Agricultural Research (INRA) from September 2011. I am now interested on the processes controlling water chemistry in headwater catchments by studying various catchment signatures and using different modelling approaches from lumped conceptual to fully distributed models. I am co-coordinator of the long-term Environmental Research Observatory AgrHys (http://www6.inra.fr/ore_agrhys) part of the RBV network on Critical Zone (http://rnbv.ipgp.fr/). My medium term research project aims at focusing on the linkage of macronutrient cycles (C and N). My teaching activities are related to water and water quality monitoring in catchments, and to hydrological and hydrogeochemical processes.
