I am a physicist working on environmental problematics. I am particularly interested in the interactions of a fluid flow with its boundaries, or with an obstacle. I study how these boundaries affect the flow, and how they affect the transport of particles by the flow. This mostly involves tools from non-linear physics and fluid dynamics.


Research interests


Since September 2017 I am working on erosion by dissolution. The flow of a fluid over a solid body is determined by the shape of the body, which imposes its boundaries to the fluid. If the body is soluble, its shape changes through the dissolution. In turn, this change of the fluid boundary affects the flow. We study this feedback mechanism between the flow and the dissolution.

During my first postdoc, at the Bioengineering Laboratory in Jacques Dumais's group, I worked on fog collection. In the driest areas of northern Chile and Peru, people hang nets across the fog flow to collect its fresh water. We study how these nets could be optimised.

My PhD focused on groundwater flow dynamics. We tried to understand how a groundwater flow can generate rapid flooding. We are now investigating the influence of the flow boundaries on its dynamics.

During a 3-months internship in Doug Jerolmack's group on river deltas morphology, I studied experimentally how a river builds and forms its own delta.
