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 (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) morphological stability and dynamics of ice-ocean interfaces, (iii) dynamics of subglacial lakes, (iv) dynamics of subglacial water environments on icy moons, (v) wave–mean-flow interactions and (vi) statistical learning methods for reduced-order climate modelling.
