Muriel   THOMASSET Ph.D

Research engineer

Muriel supported her thesis in 1998, specializing in optics and photonics, on the development of Fresnel zone plate in the X-ray field. In 1999, she worked for a small French PME specializing in fiber optic lighting. However, in 2000, she decided to return to academic research with a post-doc position at LURE synchrotron in Orsay, developing new metrology techniques for characterizing optical surfaces and diffraction gratings. In 2002, she joined the CNRS as a research engineer at LURE and started to developed metrology for 4th generation synchrotron source. Then, from 2004 to 2023, she creates a metrology laboratory for the SOLEIL synchrotron and develops techniques such as interferometry and wavefront analysis with fields of measurement connection (stitching). she has become a specialist in the characterization of diffraction gratings (measurement of variations of local line density by profilometry, roughness and height measurements by atomic force microscopy). Her developments have made possible to control and maintain the 250 optics installed on the SOLEIL synchrotron. Some of the methods developed have received COFRAC accreditation, attesting to the metrological approach adopted. In 2023, she joins the C2N Lab within the PIMENT platform to coordinate the Electrical and Physicochemical Characterization resource, as well as ongoing developments on the multiphysics platform of the Microsystems and Nanobiofluidics department for the development of interferometric and vibrometer devices.
