Tim Johnson

Tim Johnson is a physical scientist in the US EPA Office of Research and Development, National Risk Management Laboratory, Air Pollution Prevention and Control Division, (APPCD), Atmospheric Protection Branch (APB). He earned a B.S. in Mechanical Engineering and a M.S. in Industrial Engineering from the same school, with the latter involving research into the organizational and statistical aspects of quality management. Dr. Johnson joined the EPA in 2003 after earning a M.S. and his Ph.D. from the Department of Engineering and Public Policy at Carnegie Mellon University.

Research Area
Tim’s primary research interests span subjects at the interface between science and society, as well as associated issues related to data analysis and modeling. His current research involves the development of regional energy-economic models to assess the effects of technological and social change on air emissions, with an extension of this work into an integrated geospatial framework to characterize and evaluate trends in environmental quality.

Before turning to science policy, Tim worked as a statistician for the Department of Neurology at the University of Minnesota. His publications have appeared in Human Systems Management, Neurology, Muscle and Nerve, Journal of the Air and Waste Management Association, MultiCriteria Decision Analysis, Energy Policy, and Environmental Science and Technology.
