Positions

  • Since 2015 : Hosted in the Laboratoire des Radio-Isotopes (Antananarivo, Madagascar)
  • Since 2012 : Chargé de Recherches (Junior Scientist) at IRD Eco&Sols (Montpellier, France)
  • 2010-2012 : Post-doctoral soil microbiology (Esitpa, Agri’Terre, Rouen, France)
  • 2006-2010 : PhD in soil ecology (University of Rouen, France)
  • 2005-2006 : Master Ecology & Environment (University Paris Sud Orsay)

Skills

I’m a soil functional ecologist working on biological regulation on key ecosystems functions:

  • organic matter decomposition,
  • nutrient (nitrogen and phosphorus) recycling,
  • microbial activity and composition,
  • plant growth and nutrition,
  • plant tolerance against pests.

Currently, I’m studying the soil microbial loop (i.e. the effect of soil bacteria-bacterivore interactions on plant performances) in upland rice agro-ecosystem in Madagascar where I’m assigned since February 2015. I currently coordinate the projects INDICE (Agropolis Funding) and BAC-RIP (EC2CO funding).
