Thesis in ecology at Rennes in 1990, HDR (Accreditation to supervise research) in life sciences at Montpellier in 2006.

Posts held: Lamto Tropical Ecology Station, Ivory Coast (1986-1988), French Institute of Pondichéry, India (1991-1992). Joined the IRD in 1993 and appointed to Martinique (1993-2002), Montpellier (2002-2012) and then Madagascar (2013-2017)..

Closely involved in teaching in Montpellier (University, Montpellier SupAgro as Consultant Professor 2009-2012) and in Madagascar (University, School of Agronomy)..


My research is part of the study of macrofauna functions in tropical soils in interaction with the other soil biotic components with respect to a certain number of ecosystem services provides by the agrosystems. It sets out to gain a better understanding of the mechanisms through which soil engineers affect primary production services, nutrient recycling, provision of habitats (for the microorganisms) and climate regulation through carbon sequestration.

My current research programme concerns the study of the role of fauna activities on organic matter dynamics, N and P nutrient flows and greenhouse gas flows, mainly in Madagascar where I have been working since February 2013.

I also aim to propose innovations in tropical agriculture based on the intensification of soil ecological processes.
