Engineer in Ecology and Doctor in science and technology with mention in chemistry. He completed his PhD at the “Plataforma Solar de Almería”, Spain and the National Atomic Energy Commission, Argentina. He worked for the company “SURSOLAR” developing renwable energy projects in Argentina. He has directed/co-directed several research projects in the solar thermal area. He has more than 20 international scientific publications and is the author/co-author of 6 books related to solar energy. He was an adjoint professor at UTN and associate at UNSAM. He has been jury and director of several master's and PhD thesis. He was a consultant for the PTB (Institute of Technical Physics of Germany), Fundación Bariloche, CEERD (Center for the rational and efficient use of European energy), UNEP (United Nations Environmental Program) , UNDP (United Nations Development Program)and advisor to the Undersecretary of Renewable Energies of Argentina in the solar thermal area. He has been secretary of the solar thermal committee of IRAM, Argentina and technical expert of the OAA (Argentine Accreditation Body). He was finalist in several solar thermal innovation contests. He is currently president of Solarmate SA, a company dedicated to the manufacture of portable solar products, the development of services related to solar thermal energy in industries, and training in renewable energies. He also serves as Senior advisor of the Thermosolar Panama project in charge of the SNE of Panama and UNEP, and is a professor of the Diploma in Solar Thermal Energy of the National Technological University of Panamá.
