CHRISTIAN MASSARI is a Senior Scientist at the Research Institute for Geo-hydrological Protection of the National Research Council (CNR) in Italy. He earned his Master’s degree in Environmental Engineering in 2008, followed by a Ph.D. in Hydraulic Engineering from the University of Perugia in 2012. Since 2017, he has been a permanent researcher at CNR-IRPI working in the field of hydrology, eco-hydrology and land data assimilation. As the responsible of the Eco-hydrology Laboratory (Eco-hydrology Lab) at the CNR, Massari’s research delves into process understanding of water cycle extremes such as droughts and floods, their interactions with the carbon cycle and human activities as well as methods to monitor and forecast them using advanced monitoring techniques, models, remote sensing data and data assimilation. His work emphasizes the development of innovative techniques for efficient water resource management, spanning local, regional, and global scales. Massari employs cutting-edge methods to leverage Earth Observation data within land surface and eco-hydrological models. He has authored over 80 papers in peer-reviewed journals and has played principal investigator (PI) and co-investigator (Co-I) roles in over 20 projects funded by national and international calls and International Space Agencies. Massari was part of the team that received the ESA-Copernicus Excellence Award in 2022. He has also been involved in various professional organizations, including serving on the American Geophysical Union Technical Committee of Precipitation from 2019 to 2022, acting as Secretary of the Italian Hydrological Society since 2023, and becoming a member of the International Society for Photogrammetry and Remote Sensing in 2022. Massari was listed in the 2023 in the top 2% of the world’s best scientists, compiled by Stanford University and published on October 4th 2023. Furthermore, Massari is engaged with the International Association of Hydrological Sciences (IAHS), contributing to groups focused on drought in the Anthropocene and drought in mountainous regions. He serves as an Associate Editor for the Journal of Hydrology, reflecting his dedication to advancing the field of hydrology through research and editorial contributions.
