Welcome !

We have a PhD opening in our group (start date: fall 2025)! Check out the details here. This exciting project will investigate how ice melts in oceans using laboratory experiments. A graduate internship in our group in spring 2025 would be ideal for PhD candidates. Note that we also welcome postdoc applications. Applications are open until the position is filled or january 31st, 2025.

I am an assistant professor of physical oceanography and physics at the Université de Lyon and at the Laboratoire de Physique of ENS de Lyon. I am a physicist with expertise in geophysical fluid dynamics, physical oceanography and ice-ocean interactions. My work aims to discover how turbulence (the root cause of many unsolved problems in geophysical and astrophysical fluid dynamics), waves, phase changes (primarily resulting from ice ablation) and large-scale flows interact and shape the environment we live in. I specialize in the analysis of idealized complex flows (inspired by nature) using reduced-order models, turbulence-resolving numerical simulations and laboratory experiments (since joining ENS de Lyon). Local collaborators are Romain Volk, Sylvain Joubaud, Antoine Venaille, Julien Salort and Francesca Chillà. They have expertise in turbulence research, laboratory experiments, geophysical fluid dynamics, statistical mechanics and topology.

Current research interests include: (i) modelling of the ice-shelf–ocean boundary layer, (ii) multi-stability of ice-shelf ocean cavities, (iii) morphological stability and dynamics of ice-ocean interfaces, (iv) dynamics of subglacial lakes, (v) dynamics of subglacial water environments on icy moons, (vi) wave–mean-flow interactions and (vii) statistical learning methods for reduced-order climate modelling.
