Prof. Dr. Jon Chorover is a professor in the Department of Soil, Water and Environmental Science at the University of Arizona where he leads a research and teaching program in soil chemistry and biogeochemistry. He received a B.S. in Environmental Science from the University of Michigan (1983), and then an M.S. in Forest Science (1988) and a Ph.D. in Soil Science/Chemistry (1993) from University of California, Berkeley. He received a US NSF International Postdoctoral Fellowship to work in the Department of Chemistry at University of Geneva, Switzerland (1994-1995) and was then appointed Assistant and Associate Professor of Environmental Soil Chemistry in the Department of Crop and Soil Science at the Pennsylvania State University (1995-2001). He moved to the University of Arizona in 2001. Dr. Chorover was in 2007 a visiting professor in the Department of Environmental Science, Swiss Federal Institute for Technology (ETH) in Zurich, was Associate Editor, Soil Chemistry Division (S-2) for the Soil Science Society of America Journal from 1999-2005, and is now Joint Editor-in-Chief of Geoderma (A Global Journal of Soil Science). He currently serves as Chair of the Soils and Environmental Quality Division (S-11) of the Soil Science Society of America. He is working with interdisciplinary and international working groups to establish a prominent place for soil chemistry in the broader realm of environmental and earth sciences seeking to achieve the goal of an integrated understanding of earth surface processes. Dr. Chorover's specific scientific interests relate to how mineral-organic interactions influence the weathering of soils and the speciation of pollutants. His experimental approach employs a wide range of macroscopic to molecular-scale techniques to probe the coupled processes that control soil chemical dynamics. He is author or co-author of over 60 scientific journal publications. Additional information and links to publications can be found at Dr. Chorover’s website http://cals.arizona.edu/swes/chorover_lab/
