Jean E. McLain, Ph.D.

Associate Director

Jean E. McLain is the Associate Director of the University of Arizona Water Resources Research Center and an Associate Research Scientist at the Water Resources Research Center and the Department of Soil, Water and Environmental Science.

With a strong focus on environmental microbiology Dr. McLain's research program is directed towards establishing impacts of anthropogenic stressors on microbiological presence and function in soil and water and identifying linkages between microbes in the natural environment and human health. Recent studies include examining the potential for trace contaminants in degraded irrigation water and biosolids to induce development of antibiotic resistance in bacteria; and performing molecular and cultural analyses of bacterial regrowth, survival, and transport in irrigation water and soils to establish links to fresh produce safety. Dr. McLain received her doctorate from Duke University in Microbial Ecology after earning a Master’s Degree in Forest Science from Yale University and a Bachelor of Science degree in Forestry from the University of Vermont.
