A Short Biography:

Professor Froines joined the faculty of the School of Public Health in 1981. He received a B.S. in chemistry from UC Berkeley (1963), M.S. in chemistry (1964) and Ph.D. in physical-organic chemistry (1967) from Yale University. He conducted postdoctoral research at the Royal Institution of Great Britain under Nobel Laureate, Sir George Porter from 1966-68. Before coming to the UCLA School of Public Health, Dr. Froines was Assistant Professor of Chemistry at the University of Oregon and later served as Director of Toxic Substances at the Occupational Safety and Health Administration and Deputy Director of the National Institute for Occupational Safety and Health. Dr. Froines served as the Director of the Center for Occupational and Environmental Health for 25 years and is currently the Director of the Southern California Particle Center and Supersite. He is Associate Director of the Southern California Environmental Health Sciences Center and the Director of the UCLA Fogarty Program in Occupational and Environmental Health. He is Director of the Sustainable Technology and Policy Program. He serves on three advisory committees of the South Coast Air Quality Management District. Dr. Froines' area of expertise is toxicology and exposure assessment. His research interests are in the qualitative and quantitative characterization of risk factors in environmental and occupational health.

Dr. Froines chairs the State of California's Scientific Review Panel; the central review panel at the State level for identifying toxic air contaminants.
