I hold a Master in agronomy (“ingénieur agronome”, in 2000), a MSc in soil science (2001), a PhD (2004) and I received my Habilitation in 2016. I joined Bordeaux Sciences Agro in 2005, first as Associate Professor and, since 2016, as full Professor. I have been visiting scientist at McGill University (Montréal, Canada) during my sabbatical in 2013-2014. I teach agroecosystem management, cropping system design, farming system analysis, as well as some global agronomy. I pay a specific attention to agroecological approaches and to organic farming.
I’m interested in how human activities and agriculture dominate global nutrient cycles. In particular, I’m fascinated how agriculture has shaped nitrogen and phosphorus cycles in a range of scales, from the district to the planet. Complimentary, I try to understand how these cycles could be better closed. To do so, I pay a specific attention to material flows in food chains and get some inspiration from both agronomy and industrial ecology. I combine a range of methods such as field works, surveys, data mining, and modelling. My current works deal with phosphorus flows in global food and feed trade, crop and livestock reconnection at the district scale in Europe, and agent-based modelling to simulate material flows in local food chains. I also coordinate a project on organic farming development, nutrient cycles and global food security.
