I did my PhD at Paris Observatory in the team ERGA/LERMA. I worked on the developements of theoretical tools for experimental gravity, and applied them to the study of three experiments: the detection of gravitational waves and of the Lense Thirring effect (HYPER) with atom interferometers and matter-wave cavities. Then I worked one year as assistant professor in Syrte/Paris Observatory. I am now a research fellow in the Advanced Concepts Team in the European Space Agency. Here I started working on vibrating systems in general relativity and relativistic positioning systems.
