Welcome!

I am Associate Professor at Princeton University, in the Mechanical and Aerospace Engineering Department and the High Meadows Environmental Institute.

We work on fundamental fluid dynamics with an emphasis on non-linear and multi-scale systems. I am focusing on fundamental physics problems, motivated by their importance in environmental and industrial applications, as diverse as the statistics of waves in the ocean, the importance of small scale waves on ocean remote sensing, floating ice sheets, gas transfer by surface breaking waves in the ocean, sea spray aerosol generation, aerosol process and nucleation in the atmosphere, particles dynamics in turbulence, as well as the importance of waves in offshore wind energy.

We design and develop complementary laboratory and numerical experiments to propose simple physical models describing the processes at play.
