ABOUT ME

I am working on some of the most puzzling aspects of cosmology like the acceleration of the expansion of the Universe in the last few billion years of its existence. This requires combining a lot of theoretical aspects, e.g. from cosmology to quantum field theory. I have been working in this field for quite a few years although I still dabble in other aspects of theoretical physics from time to time. I cannot always resist designing supersymmetric models... I obtained my PhD from the Pierre et Marie Curie University and my habilitation from Paris Sud. I have also been lucky enough to be a post doctoral fellow at both DAMTP Cambridge and CERN. I belong to the "beyond the standard model" research group at IPhT Saclay.
