Dr. Marc Guevara holds B.S. in Industrial Engineering (Polytechnic University of Catalonia, Spain, 2010) and PhD in Environmental Engineering (Polytechnic University of Catalonia, Spain, 2014). He is a postdoc researcher with 13 years’ experience in the areas of emission and air quality modelling. In 2010, he was enrolled as support engineer at the Earth Sciences Department of the Barcelona Supercomputing Center (BSC), in 2015 moved to the postdoctoral researcher position at BSC and since January 2024 he is the team leader of the emission modelling team at the atmospheric composition group. His main expertise includes high resolution atmospheric emission modelling (development, evaluation and improvement), air quality modelling and environmental impact assessment. He coordinates the development of the in-house HERMES emission model, which is the emission core of the Spanish CALIOPE operational air quality forecast system. He is co-chair of the Emissions Working Group of the FAIRMODE community and member of the GEIA Scientific Steering Committee. He coordinated the VITALISE national project (PID2019-108086RA-I00) and the CAMS_COP066 European Copernicus service. During the last years he has participated in multiple European H2020 and Horizon Europe projects (AQ-WATCH, CoCO2, CORSO, CAMEO, MARCHES, RI-URBANS) and Copernicus contracts (CAMS_81, CAMS_81 phase ii, CAMS2_61, CAMS2_40). He has co-authored more than 30 papers in international scientific journals (26h-index and 1999 Citations), 1 book-chapter and several communications to International conferences. He has co-directed 1 PhD thesis and is currently directing another PhD thesis. He has been acting since 2020 as associate professor at the Department of Project and Construction Engineering of the Polytechnic University of Catalonia.
