MARCY-L'ETOILE

En résumé

Over the last 10 years, my research and development activities gave me a strong background in semiconductor and nanostructures physics, LED lighting, optics and photonics, cleanroom nanofabrication and characterization, with a deep expertise in nitride materials.

My goal is to continue using and developing my theoretical and experimental skills in the field of research and innovation in industry to contribute in the development of the latest technological advances. The fields of LED lighting, optics and photonics, semiconductors physics or biomedical instrumentation passionate me. I am right now discovering this last activity at BioMérieux where I can apply my knowledge in optics and physics to lead an innovating project in diagnostics.
