Graduate in Physics at Complutense University in Madrid (1999) and PhD at University of Valladolid in 2005. For 2 years he was postdoctoral fellow at the Meteorological Institute, University of Munich (Germany), where he participated in projects such as SAMUM and EARLINET. Then he obtained a postdoctoral researcher position at the Group of Atmospheric Optics, University of Valladolid (Spain) within the “Juan de la Cierva” program of the Spanish Research Council (2008). His research is concentrated in the investigation of the atmospheric aerosol by optical methods, regarding aerosol characterization, data quality assurance and field campaigns. Especial interest is devoted to desert dust and polar regions. He has more than 90 peer-reviewed publications in SCI journals and received the 3M Foundation Award 2006 for Environmental science. Currently he is in charge of the operations, calibration and quality assurance of the Iberian Network for Sun photometer Aerosol Measurements (RIMA), federated to AERONET and integrated into ACTRIS. In 2011 he obtained a researcher position at GOA-UVA within the “Ramon y Cajal” program of the Spanish Research Council. He is the Spanish representative in the Atmosphere Working Group of the International Arctic Science Committee (IASC). Since 2023 is full professor at the University of Valladolid.
