Physics and Properties of Nanostructures

Research


My research activities focus on the optical properties and appearance of materials at different scales.

I am the assistant director of the French research group, GDR CNRS 2044 APPAMAT.

I directed with Pierre Boulenguez the collective book: Quand la matière diffuse la lumière, Les Presses des Mines, 2019, 479 pp.

Teaching


I teach lighting at ENSI Poitiers.

I am a contributor to the French Light ZOOM Lumière website dedicated to lighting.
