In 2003, Rémi Métivier graduated from the École Nationale Supérieure de Chimie de Paris. He holds a thesis in Physical Chemistry at the École Normale Supérieure in Cachan. Fascinated by the way the molecules interact with each other, he joined the University of Mainz, Germany, to learn about single molecule spectroscopy. “There is something magical in this technique that allows one to observe the molecules one by one”. On his return to France in 2005, the scientist joined the CNRS and joined the laboratory Photophysics and photochemistry supramolecular and macromolecular in Cachan. Using his know-how acquired in the field of spectroscopy, he is now interested in the development, study and modelling of materials capable of changing state under the effect of light. “By combining the functions of several molecules, we try to bring out nanomaterials with unprecedented properties”. A field of research that could contribute to a tenfold increase in the storage capacity of future “all-optical” computers. (source)
