Hi, I’m Andrea Citrini, a hydrologist and hydrogeologist specializing in water resources, climate change, and groundwater sustainability. I am currently a Postdoctoral Researcher in the Environmental Studies Program at the University of California, Santa Barbara (UCSB), where my research focuses on understanding how climate change and human activities are reshaping freshwater availability across regional and global scales.

I earned my PhD in Earth Sciences from the University of Milan, where I investigated the impacts of climate change on alpine hydrological systems through numerical modelling. My academic background combines hydrogeology, hydrology, and environmental sciences, with research ranging from groundwater and karst systems to snow hydrology, streamflow dynamics, and water resources management.

Over the years, I have conducted research in Italy, Cyprus, and the United States, developing expertise in hydrological modelling, remote sensing, climate data analysis, and large-scale geospatial modelling. My current work integrates Earth observation, global hydrological models, and climate projections to investigate water scarcity, groundwater depletion, environmental flow requirements, and adaptation strategies aimed at improving the resilience of both natural and human water systems.

Beyond research, I am passionate about communicating water science and making complex hydrological challenges accessible to a broader audience. I believe that rigorous science should not only advance our understanding of the Earth system but also provide practical knowledge to support sustainable water management, informed policy, and resilient communities.

Outside academia, I enjoy spending time outdoors through running, hiking, soccer, and mountaineering—activities that continually remind me of the close connection between landscapes, climate, and water.

I’m also proud to serve as Co-Chair of the Early Career Hydrogeologists’ Network (ECHN) of the International Association of Hydrogeologists (IAH) – Italy chapter. In this role, I help foster collaboration, support young professionals, and promote science communication in the hydrogeology community.
