Michael E. Essington is professor of soil and water chemistry in the Institute of Agriculture at the University of Tennessee in Knoxville. In addition to teaching courses in soil chemistry and clay mineralogy, his special research interests center on the role of aqueous speciation in environmental chemistry, with particular emphasis on trace element adsorption and precipitation phenomena. These interests have resulted in more than 200 publications and technical reports. Dr. Essington received his BSc in agriculture from New Mexico State University in 1980 and his PhD in soil science from the University of California, Riverside, in 1985. He was a research scientist at the Western Research Institute in Laramie, Wyoming, from 1985 to 1990 and has been at the University of Tennessee since then. He is a member of the Soil Science Society of America, the American Society of Agronomy, Sigma Xi, and Gamma Sigma Delta. He is a fellow of the Soil Science Society of America and the American Society of Agronomy. Dr. Essington's professional activities include serving as an associate editor and technical editor for the Soil Science Society of America Journal and as soil chemistry division chair and member of the board of directors for the Soil Science Society of America.
