Biography, interests and publications
Short Bio: Mushegh Rafayelyan obtained his bachelor’s and master’s degrees at Yerevan State University (Armenia) in 2010 and 2012 respectively. In 2015 he obtained a PhD in Theoretical Physics from the same university (Thesis: “Optical properties of anisotropic metamaterials and metamaterial based cholesteric liquid crystals”). In 2017 he obtained a PhD in Lasers, Materials and Nanoscience from University of Bordeaux (France) (Thesis: “Singular beam shaping from spin-orbit flat optics”, supervised by Etienne Brasselet). Since 2018 he is a postdoctoral researcher in Laboratoire Kastler-Brossel, at Ecole Normale SupÃ©rieure (ENS, Paris), in the group of Sylvain Gigan, working on optical computing. In general, his research interests focus on beam shaping, optical imaging, optical computing and machine learning, light-matter interactions, liquid crystal topological defects, singular optics, and nonlinear optics.
