Jon Chorover is Professor and Head, Department of Soil, Water and Environmental Science at the University of Arizona (UA). He received his B.S. (Environmental Science) from University of Michigan, and M.S. (Forest Science) and Ph.D. (Soil and Water Chemistry) from UC Berkeley, worked as an NSF postdoctoral fellow in Analytical Chemistry at University of Geneva, and was on the faculty of Penn State University before joining the faculty of University of Arizona. His research group explores the biogeochemistry of soil, sediment and water through laboratory and field-based experiments probed with advanced analytical chemistry techniques.  Of particular interest is resolving how mineral-organic interactions influence the weathering of soils, the stabilization of organic carbon, and the speciation, mobility and bioaccessibility of pollutants.  He directs a core analytical chemistry facility, the Arizona Laboratory for Emerging Contaminants ( and serves as PI of the UA-led, NSF-funded Santa Catalina Mountains – Jemez River Basin Critical Zone Observatory (

I teach undergraduate and graduate classes in Environmental Soil and Water Chemistry (SWES 462/562), Advanced Soil and Water Chemistry (SWES 563), and Molecular Biogeochemistry (SWES 568).

Research Synopsis

Key Interests:
My research interests relate to biogeochemical processes occurring in soil, sediment and water. My lab group applies the tools of analytical chemistry - particularly mass spectrometry and molecular spectroscopy - in field, mesocosm and bench-scale experiments. An overarching goal is to elucidate coupled biological and geochemical processes that influence the form and mobility of metal(loid)s and organic molecules in the earth’s near-surface environment.
