Since 2014, Sylvain Gigan is full professor at Sorbonne Université, and group leader in Laboratoire Kastler-Brossel, at Ecole Normale Supérieure (ENS, Paris). His research interests range from fundamental investigations of light propagation in complex media, biomedical imaging, sensing, signal processing, to quantum optics and quantum informations in complex media.

His group deals with light propagation in complex media, mainly disordered photonic systems where light is scattered in a very complex way, such as paint layers, paper, or biological tissues. Multiple scattering of coherent light generates extremely complex interference patterns, called speckle. But despite the enormous complexity of the scattering process, we can exploit and control light propagation, in particular thanks to spatial light modulators. Our approach is particularly interesting for imaging, light-matter interactions, signal processing, but also as windows to understand subtle mesoscopic physics effects.
