I am a member of the CNRS research staff, and currently head of the galaxies, high-energy astrophysics and cosmology group at the Institut de Recherche en Astrophysique et Planétologie (IRAP, UMR CNRS 5277, Université de Toulouse), part of Observatoire Midi-Pyrénées. My research focuses on astrophysical fluid, plasma and magnetic phenomena in astrophysical systems ranging from the Sun to clusters of galaxies.

To get a flavour of the research topics I'm into, you may be interested in browsing through the slides of these tutorials on dynamo theory (review/lecture notes for J. Plasma. Phys. recently published here) and MHD and plasma turbulence in accretion disks given at Les Houches winter schools. Also check out this general audience conference on Chaos and Turbulence given at the Estivales de la Malepere (Aude, France).

Academic timeline

I completed a PhD in the former astrophysics laboratory of Toulouse in 2004, and after that worked for two years (2005-07) as a postdoctoral research associate in the Astrophysical Fluid Dynamics group of DAMTP (University of Cambridge). I was hired at CNRS in 2007 and have been working in IRAP Toulouse since.


My main collaborations are with

PhD students

I am currently supervising the PhD thesis of Jean Kempf (IRAP). I formely supervised the PhD theses of Subendhu Rawat (IMFT) and Antoine Riols (IRAP) with Carlo Cossu.
