Research Interests

Chief scientist and one of four associate scientific directors of the William Wiley Environmental Molecular Sciences Laboratory (EMSL) at Battelle, Pacific Northwest National Laboratories. The EMSL is a new, state of science U.S. Department of Energy user facility focused on environmental molecular science. Dr. Zachara received his Ph.D. in soil chemistry from Washington State University in 1986. His research focuses on adsorption reactions between organic, metal, and radionuclide contaminants and solid matter in the subsurface. His research has ranged from fundamental surface chemical studies to site evaluations of solute mobilization and transport in the field. He has authored or co-authored over 80 publications on these subjects. His current research is focused on the geochemical behavior of metals and radionuclides complexed by organic ligands and on the influence of subsurface microbial processes on mineral surface chemistry and reactivity in ground water.
