David Levy started his research activities in 1982-89 at The Hebrew University of Jerusalem, with the pioneering first application of the Sol-Gel process to the preparation of organically doped silica gel-glasses and reached the ICMM-CSIC in 1989. He was awarded the “First Ulrich Prize” for the most innovative work presented by a young scientist to the VI International Workshop on Glasses and Ceramics From Gels in 1991. Dr. David Levy was recently nominated by the CSIC for the “Juan Carlos I Rey” research award. He has authored or co-authored over 147 papers (> 7550 citations; h=41, G-Scholar), reviews, book chapters, Co-Editor of The Sol-Gel Handbook and several patents related to the preparation of new optical Sol-Gel materials and their applications, and was Principal Investigator for 28 Research and Industry Projects. He is member of the International Advisory Board (IAB) of the Organizing Program Committees of the “International Sol-Gel Conferences” and “Sol-Gel Optics” and “Optoelectronics and Optical Science and Technology” of the SPIE (USA), and member of the Experts Panel of the Materials Research GROWTH, FP7 and H2020 Materials and Space Programs of the EU. He was the Chair of the XVII Sol-Gel International Conference held in Madrid, 2013. He is heading the Sol-Gel Group (SGG) at ICMM, and his current research interests are optical materials (bulk materials; thin-film coatings as AR optical coatings, protection transparent coatings and functional coatings; oxide nanoparticles) and liquid crystal materials, by Sol-Gel processing and their applications. David Levy is currently Research Professor at ICMM-CSIC, Head of the Sol-Gel Group (http://www.icmm.csic.es/solgel/ ) in the Department of Photonic Materials of the Materials Science Institute of Madrid (https://www.icmm.csic.es/) and also headed 11 years the LINES of the National Institute of Aerospace Technology, INTA, where developed space materials, instrumentation and micro/nanotechnologies for space, focused on the specification, design, integration and qualification of a variety of optical instruments, which were able to be implemented on the board of a satellite.
