Professor Saiers studies water quality and supply. He runs experiments, collects observations, and develops models to illuminate how human activities affect the chemical composition of drinking water resources and alter freshwater flows within aquifers, wetlands, and river basins. His recent research projects address water quality impacts of fossil fuel development, carbon and nutrient transport through watersheds, radionuclide migration in groundwater, and carbon-dioxide removal by enhanced rock weathering. This research is executed collaboratively with students, postdoctoral associates, and faculty from Yale and other Universities. Professor Saiers’ teaching addresses various applied and theoretical aspects of surface water and groundwater hydrology.
