I focus my research on atmospheric organic aerosol. I use the state-of-the-art ACSM instrument for the real time chemical characterization of submicron particles. I am member of CEN European Working Groups (WG35 and WG44). I have participated in 33 national and international research projects: 1 as PI in Spanish National Plan, 1 as PI of subproject Marie Curie ITN. I coordinate the COST Action CA16109 COLOSSAL on fine aerosols using high time resolution techniques (74 partners from 31 countries). I co-authored 71 SCI research articles, 80% in journals in the first quartile, cited >2500 times. My h-index is 31. I co-authored 3 books, 13 book chapters, and edited a book. I co-authored 127 contributions to conferences, and reports for the European Commission, the Swiss Environmental Agency, and Regional Governments in Spain.
