Filippo Giorgi is currently an Emeritus Scientist at the Abdus Salam International Centre for Theoretical Physics (ICTP) in Trieste, Italy. From 2005 to 2024, he served as the head of the Earth System Physics section (ESP) at ICTP, where he had moved in 1998 after working at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, from 1986 to 1998. He obtained his Ph.D. from the Georgia Institute of Technology, Atlanta, Georgia, in 1986.
Giorgi is an international expert in climate modeling, climate change and its impacts from global to regional scales, extreme meteoclimatic events, biosphere–atmosphere interactions, and chemistry–climate interactions. He pioneered the field of regional climate modeling and made significant contributions to the study of regional climate change. He has authored over 420 papers in peer-reviewed scientific journals and is one of the most cited scientists in the geosciences. He is the top-rated Italian scientist in the field of Natural and Environmental Sciences, as assessed by VIA-Academy. In 2020, a study by Stanford University based on multiple bibliometric indicators ranked him 11th (out of 54,940) in the list of the most influential scientists worldwide in the field of Meteorology and Atmospheric Physics.
Giorgi has served on numerous international scientific committees, including the WMO/ICSU/IOC Joint Scientific Committee (JSC) for the World Climate Research Programme (WCRP) (2009–2014), and the Scientific Advisory Team of the WCRP Coordinated Regional Climate Downscaling Experiment (CORDEX) (Co-Chair, 2012–2018). He contributed to the first five reports of the Intergovernmental Panel on Climate Change (IPCC). From 2002 to 2008, he was one of the vice-chairs of Working Group I of the IPCC, which was awarded the 2007 Nobel Peace Prize. Giorgi has received numerous awards, including the 2018 Alexander von Humboldt Medal of the European Geosciences Union (EGU), in recognition of his outstanding contributions to climate research and to the advancement of science in developing countries. He is a member of the Italian Accademia Nazionale dei Lincei and the Istituto Veneto di Scienze, Lettere ed Arti.
Giorgi regularly engages in a wide range of outreach and educational activities, including seminars for schools and the public, as well as interviews for radio, television, and social media platforms
