Richard Johnson, Ph.D., has been promoted to professor of environmental and biomolecular systems www.ebs.ogi.edu at OHSU's OGI School of Science & Engineering. Johnson heads OGI's Center for Groundwater Research and spearheads OHSU's new initiative in the area of nanotechnology and biosensor development. Much of Johnson's research into groundwater remediation has been conducted in large model aquifers - the first and among the largest in the world - which are located on OGI's Hillsboro, Ore., campus. Johnson received a bachelor's in chemistry from the University of Washington. He joined OGI as a research technician in 1974 and subsequently entered the environmental science and engineering graduate program, earning both a master's and doctorate in environmental science. Upon earning his doctorate, Johnson was appointed assistant professor. Johnson teaches two graduate courses in groundwater modeling annually and has published numerous scientific papers.
Paul Tratnyek, Ph.D., has been promoted to professor of environmental and biomolecular systems www.ebs.ogi.edu at OHSU's OGI School of Science & Engineering. Tratnyek is an environmental chemist whose research primarily focuses on the fate, effects and remediation of pollutants in groundwater and sediments. Most recently, Tratnyek investigated how nanometer-sized particles of iron can be used to clean up various contaminants in groundwater, including chlorinated solvents and explosives. Tratnyek received a bachelor's in chemistry from Williams College and a doctorate in applied chemistry from the Colorado School of Mines. He joined the OGI faculty in 1991 as an assistant professor. Tratnyek has published numerous scientific papers, teaches two graduate courses in contaminant fate and remediation, and is frequently an invited lecturer on groundwater remediation with zero-valent iron.
