The different fundamental physics questions I worked on are mostly curiosity driven and often inspired by environmental phenomena. To study these questions, I combine laboratory experiments and theoretica modelisation to visualise and quantify the importance of different physical mechanisms at play and to make a link with microscopic/mesoscopic events with macroscopic behavior.
Here is a short description of the current activities. For previous studies, please see the publications or the PhD of the different students.
Emptying a bottle filled with a suspension
The emptying of a bottle is an everyday experience of two-phase fluid mechanics. While the alternation of rising bubbles and jets begins to be well understood, we propose to complicate the phenomenon by studying the draining of suspensions. The main objectives of our experiments is to understand the interactions between the bubbles, the fluid and the particles when a bottle is drained.

Bubbles rise in a confined granular suspension
In this work, we study the rising dynamics of bubbles rising in a Hele-Shaw cell containing a suspension of particles. An important feature I am interested in is the transition between the viscous to the inertial regime.
