Michael L. ThompsonMichael Thompson is a Professor of Soil Science at Iowa State University. For more than twenty years, he taught pedology and clay mineralogy courses, and for the past ten years he has taught courses in soil chemistry. Thompson's research has dealt wih paleosols, soil organic matter, and the fate of actinides, heavy metals, and organic contaminants in waste-amended soils. His research seeks to identify the chemical and physical conditions that favor stability, transformations, and movement of soil organic matter, anthropogenic contaminants, and clay minerals in soils. He is a Fellow of the Soil Science Society of America, the American Society of Agronomy, and the American Association for the Advancement of Science. Read More Read Less
