Quantum Engineering Toulouse

I did my PhD at Institut d’Optique (Palaiseau, France) under the supervision of Philippe Bouyer on the quantum transport of guided atomic matter waves: I worked on the direct observation of Anderson Localization in 1D with cold atoms and investigated guided atom lasers.

I spent three years as a postdoctoral fellow in the group of Tilman Pfau at the University of Stuttgart (Germany), working on dipolar quantum gases. I investigated the properties of chromium BEC trapped in 1D optical lattices and worked at the early stages of the building of a dysprosium BEC experimental setup.

I spent few months as a postdoctoral fellow in the group of Pierre Pillet at Laboratoire Aimé Cotton (Orsay, France) working on ultracold gases of Rydberg atoms.

In 2013, I was recruited as Maître de Conférences at Université Paul Sabatier - Toulouse III and joined the Cold Atoms team in Laboratoire Collisions Agrégats Réactivité.
