James N. Jensen

James Jensen is currently Associate Professor of Civil, Structural, and Environmental Engineering and Director of the Environmental Science Program at State University of New York at Buffalo . James Jensen is currently Associate Professor of Civil Engineering and Director of the Environmental Science Program at the State University of New York at Buffalo. Dr. Jensen receiv ed his B.S. in Engineering and Applied Sciences from the California Institute of Technology in 1980. He received an MSPH in 1983 and Ph.D. in 1988 from the University of North Carolina at Chapel Hill. His teaching responsibilities are in the area of env ironmental engineering, with emphasis on environmental chemistry and physicochemical processes. Dr. Jensen's current research interests are aimed at the fundamental chemistry and application of chemical oxidants in natural and engineered systems. Dr. Je nsen has served as the Chairman for the Standard Methods Joint Task Group on Oxidant Demand/Requirement. His research work has been funded by the U.S. Environmental Protection Agency, industry, and utilities.

Currently, Dr. Jensen is conducting research in two major areas related to chemical oxidation. First, research has been directed toward the development of new analytical methods for the measurement of chemical oxidants in engineered systems. This work h as resulted in the development and application of innovative methods for measuring free chlorine and monochloramine in chlorinated wastewaters. Second, Dr. Jensen and his students have investigated the application of oxidant systems to a variety of probl ems in water and wastewater treatment. This work encompasses the use of ozone for thiocyanate destruction, the kinetics of ozone demand in natural waters, and the degradation of industrial pollutants by ozone, ultraviolet irradiation, and ultrasound. In addition, Dr. Jensen is working with Dr. Weber of the Department of Civil Engineering on the combination of chemical and biological oxidation for the destruction of organics in hazardous wastes. Dr. Jensen also has collaborated with Dr. Van Benschoten o f the Department of Civil Engineering on the use of chemical oxidants for the inactivation of the zebra mussel (Dreissena polymorpha).
