I’am a CNRS senior researcher and I work within the Theoretical Physics team of the Physics Laboratory at the Ecole Normale Supérieure of Lyon.
I did my PhD in the ENS Paris on Conformal and Topological Field Theory. In the first part of my career, my research was mainly focused on Mathematical Physics and more precisely on the relation between geometry, topology and quantum field theory.
Towards the end of the 90s, motivated by scientific discussions with various colleagues and seminars, I have shifted my research interests towards Mesoscopic Physics. Because of technological progresses in nano-fabrication and radio-frequency techniques, it became possible to explore the physics of microcircuits in the regime where quantum effects are dominant and even to prepare, manipulate and measure the quantum state of electric circuits.
My present research aims at developing a theoretical framework for electron quantum optics, an emerging field that aims at the manipulation of the quantum state of single to few electrons in a conductor.
