RESEARCH TOPICS

I am interested in understanding the underlying physics of multiphase flows in porous media that is of great importance in many areas of applied science and engineering including hydrogeology, reservoir engineering, and CO₂ sequestration.

I conducted my PhD at the Institut de Mécanique des Fluides de Toulouse, where I focused on the experimental study of flow of concentrated suspensions of red blood cells in microchannels. Then, I joined the Laboratoire Charles Coulomb in Montpellier for 6 months where I worked on the fabrication of micro-devices for nanofluidics based on carbon nanotubes. From 2013 to 2017 I worked at Stanford University with Prof. Kovscek on the experimental study of multiphase flow in micromodels (i.e. at the pore-scale). In particular, I developed a micro-PIV (Particle Image Velocimetry) setup that allows us to measure velocity field in complex porous media at the pore-scale. With this setup we were able to observe complex interface dynamics at the pore scale that motivate further measurement of multiphase fluid movement. I am also interested in reactive transport.

I joined the Institut des Sciences de la Terre d’Orléans as an associate professor in 2017, I am part of the Porous Media group.
