Highlights

Catastrophic plug ruptures in networks: published in PNAS (Proceedings of the National Academy of Science USA). (2013)

In our paper on «Airways reopening through catastrophic events in a hierarchical network» we study the reopening of airways obstructed by liquid plugs in a binary tree geometry. In particular, we show that the reopening occurs through a succession of cascades of liquid plug rupture with specific spatio-temporal distribution.

Armored bubbles tailoring: selected for the front cover of Soft Matter and highlighted as one of the hot papers of the year. (2014)

In our paper entitled «Capillary tube wetting induced by particles: towards armoured bubbles tailoring», we demonstrate that stable cylindrical armoured bubbles of tailored radius and length can be simply obtained by pushing a liquid finger inside a capillary tube covered with partially wettable particles. In particular, we prove that the armoured bubble formation process relies on the minimization of interfacial energy.

Particles induced inverse Saffman-Taylor instability: accepted for publication in Phys. Rev. Lett. (2016)

In our paper entitled: «Inverse Saffman-Taylor experiments with particles lead to capillary driven instability», we demonstrate that the presence of partially wettable particles on the walls of a Hele-Shaw cell leads to a capillary driven fingering instability in a situation (air pushed by liquid) that would otherwise be stable.

Putting «Life» in order with our acoustical tweezers (2017)

Our paper entitled «Selective manipulation of microscopic particles with precursor swirling Rayleigh waves» published in Phys. Rev. Appl., has been highlighted in the Phys. Buzz of APS site Physics Central. In this paper, we show that selective manipulation of microscopic particles can be achieved with cheap, selective, flat and easily integrable  acoustic tweezers based on swirling Surface Acoustic Waves.

Streaming in droplets: paper highlighted in «Focus on fluids», Journal of Fluid Mechanics (2017)

Our paper entitled «On the influence of viscosity and caustics on acoustic streaming in sessile droplets: an experimental and a numerical study with a cost-effective method» published in J. Fluid Mech, has been highlighted in Focus on Fluids. In this paper, (i) we  study experimentally, theoretically and numerically the role played by the fluid viscosity on acoustic streaming, (ii) we show that the flow structure produced inside droplets by SAWs results from acoustic fields similar to whispering galleries in architecture and (iii) we propose an original numerical method that enables the computation of acoustic streaming inside a droplet in 3D with a simple dekstop computer.


This paper has also been highlighted by CNRS on INSIS website

Acoustofluidics 2018, held at the University of Lille / IEMN laboratory (2018)

«Folding a focalized acoustical vortex on a flat holographic transducer: Miniaturized selective acoustical tweezers» published in Science Advances (2019)

It is now possible to selectively and precisely position some micrometric particles in a standard microscopy environment with our newly designed miniaturized acoustical tweezers. More information on:

Elected junior fellow of the «Institut Universitaire de France» (Academic Institute of France) (2019)

The «Institut Universitaire de France» (IUF, Academic Institute of France), is a service of the French Ministry of Higher Education that distinguishes each year a small number of university professors for their research excellence, as evidenced by their international recognition. Only 2% of French university professors have been currently distinguished by the Institut Universitaire de France. More information on:
