RESEARCHH THEMES
1. Two-phase flows in microfluidics (dynamics and/or breakup of droplets, aging of 2D foams, acoustics of controlled foams...)
2. Two-phase flows and thermal control in microfluidics (drainage of 2D foams, droplet joystick by thermomechanical effect, separation of binary liquids under thermal gradient...)
3. Two-phase flows for decarbonized energy production (hydrogen production : bubble dynamics, waste heat recovery using a binary solution)
4. Mass transport on a surface (effect of flow on the signal received by a sensor)
5. Applied systems (liquid distributor through a hole matrix for transdermal injection, optimization of heating resistor shapes, hydrophobic/hydrophilic thermopatterning)
6. Chaotic mixing
MOBILITIES
After completing a PhD on two-dimensional turbulence and a postdoc on cavitation, I was recruited for a project focused on chaotic mixing in microfluidics. For nearly 20 years, my work has primarily centered on two-phase systems, with or without thermal control, and has recently taken a turn toward applications in decarbonized energy.
I joined the SATIE laboratory (UMR 8029) in Rennes (now ENS-Rennes) in 2002. In autumn 2008, I moved to the Gulliver UMR 7083 at ESPCI ParisTech, and then returned to Rennes in 2018 to join the IPR at the University of Rennes.

Research Projects
All the projects are detailed in the research section of the site. The figure below lists the projects I have carried out around 4 main themes. In spite of the apparent diversity of subjects, the great majority of these projects were initiated from observations or questions raised by previous projects. There is thus a continuum of questions raised ranging from thermal problems to mass transport.
