Dr. Oriol Jorba, senior researcher of the Barcelona Supercomputing Center (BSC) Atmospheric Composition group since 2016 and leader of the BSC Atmospheric Modelling group from 2008 to 2015. He has participated in projects funded by the European Commission on air quality, specifically in aerosols, (APPRAISAL, EARLINET, FIELD-AC, ACTRIS1, ACTRIS2) and in the application of atmospheric modeling in HPC (IS-ENES, IS-ENES2, RETHINK big). He has lead the research project on the development of the multiscale chemical weather forecasting system NMMB/BSC-CTM (CGL2008-02818, CGL2013-46736) which is the official model used by the Barcelona Dust Forecast Center (BDFC), the World Meteorological Organization (WMO) Regional Meteorological Center specializing in Atmospheric Sand and Dust. He has performed air quality impact assessment projects for companies (PRySMA Calidad y Medioambiente, S.A., IBERDROLA, Gas Natural, PB Powers, SGS TECNOR, S.A., INYPSA Informes y proyectos, S.A.). He has been a Spanish representative member of the management committee of COST Actions ES1002 and ES1004, and is part of the International Technical Meeting on Air Pollution Modelling and its Application (ITM) scientific committee since 2012. He is an active member of the International Cooperative for Aerosol Prediction (ICAP) and the Air Quality Modelling Evaluation International Initiative (AQMEII). Additionally, he maintains regular collaborations on aerosol modelling with the NASA Goddard Institute for Space Studies, National Center for Environmental Prediction, University of California Irvine, among others. A scientific reviewer of the Scientific Commission of the Spanish National Research Program, his research expertise includes high resolution mesoscale meteorology and air quality, development of online meteorology-chemistry models, boundary layer, atmospheric chemistry studies and environmental impact assessment. He has co-authored more than 50 papers in international scientific journals, over 100 communications in international conferences and directed 7 PhD theses. Additionally, he has been the mentor of two national FPI PhD fellowships, has been part of the research group in charge of one Marie Curie Intra-European Fellowship in the call FP7-PEOPLE-2013-IEF, and acts as supervisor for two Marie Skłodowska-Curie Individual Fellowship in the call H2020-MSCA-IF-2015 and H2020-MSCA-IF-2016.
