Professor Agustí has extensively studied the world’s oceans, including the Red Sea. She is a leading expert in phytoplankton ecology, plankton metabolism, and their role in oceanic carbon cycling. Over the past two decades, her research has focused on the impacts of global change, particularly warming, UVB radiation, acidification, and persistent pollutants on marine ecosystems. Together with her team, she investigates the vulnerability and adaptive responses of marine organisms to these stressors through environmental monitoring, sedimentary record analysis, and experimental research. Her recent work highlights the combined effects of multiple stressors and the unique adaptations of Red Sea organisms to extreme environmental conditions.
