His main field of research is the characterization of the optical, chemical and physical properties of atmospheric aerosol particles, to understand the effects that atmospheric particles have on climate and air quality. He is the scientific coordinator of the IDAEA-CSIC (Barcelona, Spain) research line aiming at studying the optical properties of atmospheric aerosol particles by both in-situ surface and remote sensing techniques. He is member of Working Groups on various initiatives for reviewing and assessing the scientific activities related to monitoring (e.g., Task Force on Measuring and Modeling – TFMM, ACTRIS WG on Level 3 data). In 2020 he received the I3 certification which recognizes the quality requirements of production and scientific-technological activity that imply an outstanding research career. He participated in a number of National and International Research Projects.
