Dr. Ángel García-Botella is a Professor of the E.T.S.I. at the Polytechnic University of Madrid. He received his degree in CC. Physics in 1995 from the University Complutense de Madrid and his doctorate in 2000. His research career focuses on the field of non-imaging optics, photometry, LED sources and vector theory of radiation transfer. He is the co-author of 30+ scientific publications, 1 book and is the co-inventor of 5 patents. Dr. Roland Winston is a leading figure in the field of nonimaging optics and its applications to solar energy. He is the inventor of the compound parabolic concentrator (CPC), used in solar energy, astronomy, and illumination. He is also a Guggenheim Fellow, a Franklin Institute medalist, past head of the University of Chicago Department of Physics, and a member of the founding faculty of University of California Merced, and he is currently the Director of UC Solar. Dr. Lun Jiang is a Research Scientist at UC Solar. His expertise is with vacuum devices, nonimaging optics and solar thermal and hybrid systems, solar cooling, and solar desalination. In his Ph.D. thesis he demonstrated two novel solar collectors that reach a working temperature above 200°C, without tracking. He led the receiver designing team for a vacuum hybrid receiver that generates both electricity and heat under 70x concentration, commissioned by Advance Research Project Agence-Energy (a segment of the U.S. Department Of Energy).
