Benjamin Grévin is a graduate of the Institut National Polytechnique de Grenoble (INPG) and of the former University Joseph Fourier Grenoble I (University Grenoble Alpes, UGA). He received the Ph.D. degree in 1998 under the supervision of Dr. Y. Berthier. His doctoral work dealt with NMR investigations of high Tc superconductors and related cuprates. After a postdoctoral stay at the Condensed Matter Research Department of Geneva University in the group of Prof. Ø. Fisher, he joined in 2000 the UMR5819 joint research center (CEA-CNRS-UGA). He was awarded the bronze medal of CNRS in 2005 and obtained the accreditation to direct research (Habilitation à diriger les recherches, HdR) in 2006. His current projects as Research Director (CNRS) deal with the development of advanced scanning probe microscopy techniques (nc-AFM/KPFM, time-resolved surface photo-voltage imaging), for local investigations of the opto-electronic properties of donor-acceptor bulk heterojunctions and molecular self-assemblies, hybrid perovskites and 2D van der Waals interfaces based on transition metal dichalcogenides.
