Research

• Environmental quality and resource sustainability are threatened by the introduction of chemicals to soil and water, where such chemicals can compromise ecosystem and human health. Research in the Seyfferth lab lies at the intersection of soil biogeochemistry and plant physiology, with an overarching goal of improving ecosystem and human heath. Current research focuses on understanding the processes occurring at the soil-plant interface that control trace-level uptake of contaminants and nutrient cycling by edible plants in a changing climate.
