Her work focuses on monitoring chemical contaminants in the environment to assess the impact of agricultural production systems on the fate and transport of chemical contaminants through the components of the agroecosystem. This research is essential for developing appropriate agronomic practices and mitigation strategies for conserving vital water and soil resources of the Mid-South. Before coming to the University of Arkansas, Dr. Willett taught Introductory Soil Science at the University of Missouri, where she also received her M.S. and Ph.D. in soil science.
