I am a theoretical fluid dynamicist, working on turbulence in geophysical systems.

I develop analytical and numerical approaches to understand the statistics and dynamics of chaotic fluid motions, waves and large-scale structures.


I am a post-doctoral fellow in the Department of Physics at the Technion, working in Anna Frishman's statistical hydrodynamics group on large-scale flows in turbulence. Previously, I did my PhD under the supervision of Laurette Tuckerman and Dwight Barkley at Sorbonne Université in Paris (at the PMMH lab - ESPCI Paris), on the transition to turbulence in shear flows. I graduated in Mechanical Engineering at Ecole Polytechnique (Paris) and in Aerospace Engineering at ISAE-Supaero (Toulouse).

My research interests include: out-of-equilibrium statistical physics, multiple-scale analysis, dynamical and stochastic systems, numerical methods, pattern formation, shear flows, internal waves, instabilities, transition to turbulence and wave turbulence.

Self-organization of turbulence

Sometimes, but not all the time, turbulence is organized. That is, chaotic fluctuations generate strong large-scale and persistent motions, like the ones we see in the atmosphere or the oceans. Find out how internal waves can drive this phenomenon here!

Phase transition to turbulence in shear flows

The conditions for turbulence to emerge in wall-bounded flows, like pipe or Couette flow, have remained a mystery for more than a century. Nowadays, we have evidence that turbulence propagates via a percolation process described by universal statistical laws. Find out more about my works on the transition to turbulence here.

Extreme events

Abrupt dynamical events can occur in chaotic systems. They can be rare but fatal. To estimate their occurrence efficiently, novel numerical methods must be designed. See here how they can be applied to shear-flow turbulence!
