Complex fluids stuff :
I am currently working in the Garbin group at Imperial College London. We are interested in the dynamics of bubble in yield-stress fluids. More specifically, we examine how they rise or get trapped depending on buoyancy-induced stress. One of our goals is to trigger bubble rise at a distance. Our work has offered us to collaborate with :
- Marco de Corato (U. Barcelone)
- John Tsamopoulos, Yannis Dimakopoulos (U. Patras)
I have formerly been working in group 1 of the physics lab of Ens de Lyon. Almost everything is done now, but some papers are still under way for these two topics:
- Resuspension of non-Brownian particles in fluids. With Sébastien Manneville, Hugues Bodiguel (LRP, U. Grenoble), Steven Meeker and Guillaume Ovarlez (LoF, U. Bordeaux/Solvay, France),
- The rheology of Waxy Crude Oils, notably at very low shear rates, with Sébastien Manneville, Michela Geri, Thibaut Divoux, and Gareth McKinley (MIT, Cambridge).
Here are other topics where my contribution is "done":
- A statistical analysis of what cornstarch does in the "stuck" unsteady state, with Sébastien Manneville and Thomas Gibaud,
- The fascinating strain-hardening properties of latex, with Sébastien & Thomas, Paul Menut (Montpellier SupAgro & Agro ParisTech), Guilherme de Oliveira Reis, Frédéric Bonfils, Laurent Vaysse (CIRAD, Montpellier) and Christian Sanchez (U. Montpellier),
- Simultaneous concentration and local velocity in a small-gap Couette geometry, with Sébastien, Steven Meeker, Hugues Bodiguel, Thomas Gallot and Vincent Grenard (the two latter people wrote almost all the code),
- Sodium caseinate gels under oscillation (LAOS), with Sébastien & Thomas, Bavand Keshavarz (formerly at MIT), Thibaut Divoux and Gareth McKinley,
- Slip, migration and confinement in model and non-model shear thickening fluids, with Annie Colin (SIMM, ESPCI Paris), Guillaume Chatté (formerly at SIMM) and Anaïs Machado (formerly at LOF, Bordeaux),
- Secondary instabilities in wormlike micellar solutions, with Sandra Lerouge (MSC, U. Paris Diderot) and Marc-Antoine Fardin (Institut Jacques Monod, U. Paris Diderot).
I have previously worked on directional freezing experiments of colloidal or nearly-colloidal suspensions (micron-sized polystyrene particles). We studied the collective inclusion behaviour during directional freezing and the effect of the boundaries on this mechanism along with Alain Pocheau, Marc Georgelin (IRPHÉ, U. Aix-Marseille) and Sylvain Deville (CREE, Saint-Gobain/CNRS).
In my younger days, I hopped on the french washing machine bandwagon for my PhD Thesis at the SPHYNX laboratory (CEA Saclay, France). More precisely :
- We examined possible links between statistical mechanics and the turbulent flow observables, in connection with the large scale slow dynamics of the experiment. This has been done with: François Daviaud (PhD advisor), Bérengère Dubrulle (unofficial co-PhD advisor), Davide Faranda and Simon Thalabard.
- A 4:1, liquid and superfluid helium von Kármán flow has been built ! I had the opportunity to participate to SHREK experiments hosted by the Service des Basses Températures in CEA Grenoble. This collaboration involves multiple researchers thoughout France:
- Bernard Rousset, Michel Bon Mardion, Pantxo Diribarne, Patrick Bonnay et Alain Girard (SBT, CEA Grenoble)
- Bernard Hébral, Philippe Roche, Matthieu Gibert (Institut Néel)
- Julien Salort, Laurent Chevillard, Mickaël Bourgoin et Bernard Castaing (Ens de Lyon)
- François et Bérengère (CEA Saclay)
- Éric Herbert (LIED, U. Paris Diderot)
- Christophe Baudet et Yves Gagne (LEGI, Grenoble)
- Thierry Lehner (Observatoire de Meudon)
I also like to hear about
- Granular Matter
- Active Matter
