Biography
Sébastien M. Popoff is a CNRS Research Scientist (Chargé de recherche) at the Institut Langevin (ESPCI Paris, PSL University, CNRS) in Paris. His research focuses on wavefront shaping and the control of light propagation in complex media, in particular multimode optical fibers and strongly scattering materials, with applications ranging from high-capacity optical communications and endoscopic imaging to quantum optics, nano-optomechanics and optical computing.
He obtained his PhD in Physics from Université Paris-Diderot (Paris 7) in 2011, for work carried out at Institut Langevin on the spatio-temporal control of light in complex media. From 2012 to 2014 he was a postdoctoral researcher in the Department of Applied Physics at Yale University, working with Hui Cao on wave transport and coherent control in disordered photonic systems. He then joined CNRS as a research fellow, first at Télécom ParisTech and subsequently at Institut Langevin, where he leads research on harnessing disorder and symmetries in multimode fibers and scattering media for imaging, sensing, secure communications and analog photonic information processing.
