Expertise

With a fluid mechanics background, I develop research about the influence of hydrodynamics on the functioning and structuration of benthic communities. My first focus goes to the role of connectivity on resilience capacity of benthic invertebrates meta-communities (polychaetes, gorgonians, corals) in the context of global change and protection actions. I therefore develop mechanistic numerical models for meta-populations and meta-communities in which connectivity is quantified using numerical simulations of Lagrangian dispersal including the effect of larval motility derived from experimental studies. My second reaserch line concerns the dynamics of micro-organisms communities living at the water-sediment interface and their associated biogeochemical functions under extreme physical forcing (intertidal mudflat biofilm dynamics, early diagenesis under swell and wind waves events in the nearshore zone). I hence develop numerical models coupling turbulence dynamics in bottom boundary layers and early diagenesis and carry out experiments on organic matter degradation in which turbulence unsteadiness is controlled.
