RICARDO VERGAZ BENITO received MScs degrees in Physics and Electronics Engineering and a Ph.D. in Science (Physics) at the University of Valladolid, Spain. In 2001, he joined GDAF-UC3M at Universidad Carlos III de Madrid (UC3M), where he is currently an associate professor of Electronics and Photonics. His research lines are: characterization of electrooptic materials and devices and their applications in engineering, including new generation solar cells; design and characterization of novel metasurfaces and nanostructures to improve their optical and electrical performance by light handling; and applications for assistive technologies. He has been the supervisor of four Ph.D. theses in the last 10 years, and the co-author of more than 50 papers indexed in JCR and more than 120 communications in congresses. He is the co-inventor of two patents (one in exploitation) and has one Software Registration.
