Profile Summary
Research engineer at Observatoire de Paris since 2008, I am currently in charge of the Instrumentation Group at GEPI laboratory. I am currently involved in MICADO, the first light imager project for the ELT, as the responsible for the optical design of the wavefront sensor of the SCAO module, and as the workpackage manager of the SCAO Calibration Unit. I have been working on ELT instruments as an optical engineer for more than 13 years now, and I am now specialized in adaptive optics and wavefront sensing applications.
