I am a research scientist with more than 15 years of experience in the fields of plant and soil sciences, environmental health, natural resources management and environmental archaeology. After working in Australia, for the CSIRO, Land and Water, from 1997 to 2003, I was appointed as a research scientist with the Institut de Recherche pour le Développement (IRD) in December 2004. I have been posted in Vientiane, Lao P.D.R. from April 2005 to August 2010, as seconded staff to IWMI's regional office, and then again since September 2011. I have written and co-written several successful research proposals (GRDC (Australia), CPWF, Michelin-IFC (France), ANR (France)). Between 2009 and 2011, I have coordinated, at the national level, the Multi-Scale Environmental Change (MSEC) network and the ANR-AiRD-“Sédentarités autour du Mékong” programme in Lao P.D.R. I currently am the coordinator of the ANR-Ecosfix for Bioemco in Laos. I am a section editor for the journal Plant and Soil and I have published over 60 scientific articles / book chapters among which 38 in peer-reviewed international journals, 27 dealing with roots/soil structure. I have also supervised under- and post-graduate students, including 3 PhDs. My current research interests include the complex interactions between land use / land use change, plant growth and the water and carbon cycles.
