Francis Orvain is an associate professor in the team ‘Diversity and Interaction in Coastal Ecosystems’ of BOREA. He is 39 years old and has published 29 ranked-A papers with a H-index of 13. He is a specialist of the relationships between sedimentary habitats and benthic communities (macrozoobenthos and microphytobenthos) at the sediment/water interface in coastal ecosystems: processes of bioturbation, biostabilisation (EPS) and erosion. He is a numerical modeler of bioturbation/erosion processes with many papers on the subject. He was task leader in the ANR project VASIREMI (2007-2011) and leader of a regional project named GECO-GECO (‘Ecosystem management to guide the cockle fishing”). He is also leader of the project Seine-Aval 5 (2014-2017) BARBES (Biological Association in Relation with sediment transport: Development of a new model of Bioturbation caused by ecosystem Engineers in Seine estuary). In all these projects, he performed lab and field erosion to focus on the role played by microphytobenthos and the macrozoobenthic community on sediment, chl a biomass and microorganism resuspension. These data are collected for developing mechanistic models of bioturbation. He is also a member of the national network RESOMAR and supervises an EC2CO program called UNdER-PRESSURE (a project aiming at providing ecological indicators of the impact of fishing effort on benthic communities and sediment habitat). In many project (GECO-GECO, SA5-BARBES, ANR GIGASSAT on the impact of global warming on mass mortalities of the oyster Crassostrea gigas), he used to map macrozoobenthic and microphytobenthic communities in estuarine ecosystems for deciphering the estuarine ecosystem functioning and the benthos/pelagos coupling.
