I am a Senior Researcher at CNRS (the French National Center for Scientific Research), working at the Fluid Mechanics Institute of Toulouse (IMFT).

My research focuses on several fundamental aspects of hydrodynamics and turbulence in two-phase flows and inhomogeneous fluids, mostly studied by means of computational and theoretical approaches. I also closely collaborate with experimentalists and occasionally directly supervise simple experiments myself.

I am especially involved in two main areas:

• the dynamics of particles, drops and bubbles, most notably:
  – the determination of forces acting on these bodies when they move in non-uniform or time-dependent flows;
  – their hydrodynamic interactions with similar neighboring entities or walls;
  – the motion and possible trapping of bubbles and particles in vortical structures and the way they may collectively alter vortices or generate specific flow patterns;         
  – how phase change (evaporation, dissolution, boiling, condensation) or contamination by surfactants modifies the dynamics of rising bubbles and spreading drops; 
  – the topological changes that may be experienced by large rising bubbles or drops spreading on a liquid surface in the presence of Marangoni effect;
  – the path instability and subsequent style of paths of bubbles and rigid bodies freely moving under the effect of an external force (such as gravity/ buoyancy);   
  – the dynamics of particles and bubbles crossing a sharp interface separating immiscible liquids;
  – the specific flow structure and dynamics of rigid particles settling or rising in density-stratified or rapidly-rotating fluids. 

• the structure, mixing properties and near-surface interactions of non-standard inhomogeneous turbulence, especially:
  – inter-component transfers and boundary-layer structure in free-surface turbulence;        
  – high-Schmidt-number mass transfer across walls and free surfaces;       
  – the peculiar structure of turbulence and mean current beneath surface waves;
  – the generation of surface waves on viscous liquids by a turbulent air flow;             
  – the physics of gravitationally-induced turbulence in open and confined geometries;     
  – the dynamics of confined high-Reynolds-number gravity currents.  

• other topics I am or have been involved in include:
  –  complex two-phase flows (liquid-liquid phase inversion, sudden emptying of liquid-filled containers);  
  – fluid slip at rigid surfaces (influence on the dynamics of bluff-body wakes, generalization of the Navier condition to rough surfaces, drag reduction by air-filled micro-cavities);  
  – dynamics of droplet chains and living cells in microchannels;  
  – numerical techniques for two-phase flows (interface capture, modeling of viscous stresses).

To study these phenomena, I use and sometimes develop a variety of techniques and methodologies. Some of them are analytical, including perturbation approaches or vector field decomposition, others are computational. In particular, I developed, first by myself, then with successive generations of students and colleagues, the in-house computational JADIM code that solves the Navier-Stokes equations, possibly coupled with the transport of passive or active scalars such as temperature, density or surfactant concentration. This code includes boundary-fitted as well as fixed-grid approaches thanks to which interfacial phenomena may be accurately captured. It allows direct numerical simulations of two- and three-phase flows, possibly with rigid moving bodies and interfacial topological changes, from viscous-dominated to fully turbulent regimes.

Together with my students and colleagues, I employ these various and complementary tools to dissect and model the physical mechanisms at play in the above types of flow. This frequently yields predictions in the form of generic laws that are then used to understand, predict and sometimes optimize the properties of complex flows of engineering or geophysical relevance.  

More specifically, through various collaborations with industrial and institutional partners, I have been directly involved in a variety of problems related to nuclear safety (cooling systems, accident scenarios), steelmaking, chemical engineering (gas separation, fluidization, microfluidics), oil recovery (mixing in wellbores), transportation (interfacial phenomena in aircraft and launcher tanks, bubble-induced drag reduction), defense (bubbly wakes, compartment emptying, inertial confinement), air-sea interactions (wind-induced waves and turbulence, CO₂ capture), marine pollution (microplastics, oil spills) and volcanology (turbulent and viscous mixing in magmatic chimneys).
