Dr Loreto Valenzuela received the degrees in Physics (1994) and Electronics Engineering (1996) from the Univ. of Granada (Spain) and her Ph.D. (2007) from Univ. of Almería (Spain). She has a permanent position as Senior Research at Plataforma Solar de Almería (CIEMAT-PSA, Spain). Her work during last 23 years has been related to design, modelling, simulation, process control, development of testing procedures and test benches, and experimental evaluation of complete prototypes and components for concentrating solar thermal energy technologies, mainly related to parabolic troughs and linear Fresnel solar collectors. She has been involved in 28 R+D projects (in 6 as principal investigator) and more than 30 bilateral R+D contracts with industries or public entities. Co-author of 95 journal papers or conference proceedings. Member of Spanish and international standardization committees defining standards for solar thermal power plants and their components (AENOR/CTN206/SC117 and IEC TC117). She also leads the sub-programme «Line Focusing Sytems» of the joint programme on Concentrating Solar Power of the European Energy Research Alliance (EERA) since 2014.
