Sarah Fakhreddine is an environmental engineer and geochemist studying the processes that control contaminant and nutrient mobility in groundwater. Her work focuses on developing a diverse portfolio of water management solutions that account for complex biogeochemical interactions in order to protect water quality for human and ecosystem health. She is currently an Assistant Professor of Civil and Environmental Engineering at Carnegie Mellon University. Prior to her current role, she completed a postdoctoral research fellowship in sustainable water resources at the University of Texas at Austin and served as a fellow with the Environmental Defense Fund working on implementation of sustainable groundwater management practices in the Western United States. She holds a Ph.D. in Environmental Earth System Science and M.S. in Environmental Engineering and Science from Stanford University.
