Research area: Organisms-sediments/soils relationships

My goals are (i) to investigate the role of macrofaunal functional biodiversity on sediment and soil biogeochemistry and the resulting direct (bioturbation) and indirect (via microbial communities) effects on the fate of natural and anthropogenic organic matter and (2) to study the changes in structure and functioning of organisms/communities affected by anthropogenic inputs. My works realized in collaboration with EcoLab, French and foreign colleagues and students are based on both laboratory/in situ experiments and on field observations.
