Biography

Hassan is an integrated human-environmental systems researcher working as an Earth Scientist at the Joint Global Change Research Institute, a collaboration between the Pacific Northwest National Laboratory and the University of Maryland. Hassan's research focuses on discovering and leveraging multisector, multiscale energy-water-land dynamics under the global change drivers of socioeconomic, technological, and climate change. His work enables climate change mitigation, ecosystem resilience, sustainability, and resource security globally, with a particular focus on low-input environments, using integrated assessment and coupled human-Earth system models. He also researches on nature-based engineered systems and disaster risk reduction using probabilistic and process-based numerical models. Collectively, his work has contributed to advancing our understanding of the fundamental dynamics of multiple anthropogenic and natural sectors including water resources, energy production and use, land use, agriculture, greenhouse gas emissions, and atmospheric, terrestrial, and oceanic natural systems under global change. Hassan is a member of several professional bodies, including AAAS, AGU, and ASCE, and often represents the team studying global change both nationally and internationally. He holds two master's and a bachelor's in civil engineering with the highest honors.
