PhD thesis at the Chemistry Department of ENS Paris

The Ultrafast Photochemistry and Biophysical Chemistry groups of UMR PASTEUR, at the Chemistry Department of ENS Paris, seek a motivated candidate for a PhD at the interface of their activities.

A physical chemist or biophysicist profile would be particularly welcome.

The project aims at developing new analytical chemistry and fluorescence imaging methods exploiting the mechanisms and dynamics of reversibly photoswitchable fluorophores as discrimination factors. These methods will rely on a high frequency modulated excitation of the fluorophores and proper filtering of the resulting fluorescence signal. The PhD candidate will characterize experimentally the photoswitching mechanisms and dynamics of different classes of fluorophores by time-resolved spectroscopy and under high frequency modulated illumination. He (she) will in addition perform theoretical calculations in order to optimize the illumination and detection conditions of the fluorophores, depending on their photoswitching mechanism.

Un nouvel ouvrage de Bernard Valeur vient de paraître aux éditions Flammarion. Il est intitulé "Une belle histoire de la lumière et des couleurs". Cet ouvrage n'est pas un livre d'histoire des sciences mais une invitation au voyage dans le monde de la lumière et des couleurs où physique, chimie, biologie, physiologie, médecine, art, architecture, design, histoire, etc. apportent leurs éclairages. Un voyage fascinant !"
