Biography

Tim Johnson joined the EPA's Office of Research and Development in Research Triangle Park, North Carolina, as a physical scientist in 2003, after earning his Ph.D. from the Department of Engineering and Public Policy at Carnegie Mellon University. Johnson'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 work involves the development of regional energy-economic models to assess the effects of technological and social change on air emissions, with an extension of these models into an integrated spatial framework for characterization and evaluation of trends in local environmental quality.
