      Scott Fruin is Assistant Professor in Preventive Medicine, in the Division of Environmental Health. His research focuses on air pollution exposure assessment and includes field measurements in support of population-based, longitudinal health studies. Of particular interest to Dr. Fruin is better characterization of high exposure environments such as in-vehicle, near-vehicle and near-roadway environments, and the use of mobile approaches to map spatial differences in pollution. Recently, he has been measuring neighborhood exposures near the ports of Los Angeles and Long Beach. Dr. Fruin is also interested in strengthening the links between pollution measurements and health outcomes, such as adapting bioassay measurements of the biological activity of particulate matter for comparison to chronic health effects, including asthma and reduced rates of lung growth.
