The Group

I am researcher at the Laboratoire de Physique Statistique at the Ecole Normale Supérieure in Paris, working with the Non-Linear Physics Group .

My research interests lie in the fields of Turbulence, MHD turbulence, Dynamo theory, and their Astrophysical and Geophysical applications. I am interested in problems in simple geometries, and dynamical equations in their simplest form (neglecting when possible physical effects like for example compressibility) in order to get a basic understanding of the behavior of a system. In particular, I would like to address questions regarding the coupling of widely separated scales (multiscale problems); for example how does a Prandtl number (the ratio of viscosit y to diffusion coefficient) different than one can affect the large scale flow in a MHD or a stratified flow? how does a large scale magnetic field or a large scale stratification affect the small scale turbulence? Can these effects be modeled? Do they predict a behavior that is observed in nature? Analytic methods, numerical work, and experiments are equally important to address these questions.

A little bit about myself

I got my Batchelors degree in Physics at the Physics department of the University of Crete .

After which I started my Ph.D. at the Physics department of the University of Chicago . My thesis work was under the guidance of Prof. R. Rosner . It allowed me to collaborate with people from a variety of departments: Physics, Mathematics, Astrophysics, Computer science, giving me a wide perspective for research outside my own field. During my Ph.D. I attended a 10 week long summer school at the Geophysical FLuid Dynamics (GFD) program at the Woods Hole Oceanographic Institution (WHOI).

My first postdoctoral position after my Ph.D. was at the Advanced Study Program (ASP) in the National Center for Atmospheric Research (NCAR) at Boulder Colorado.

My second postdoc was in Nice, France at the L'Observatoire de la Côte d'Azur also known as Nice Observatory.

Finally I came for a postdoc/Visiting researcher position in Paris, in the Non-Linear Physics Group at the Laboratoire de Physique Statistique at the Ecole Normale Supérieure , where I finally stayed.
