Biography
Hide
Dr. Ryan’s research program focuses on the role of indoor and outdoor environmental toxicants on pediatric health, with specific focus on the impact of air pollutants on respiratory and neurobehavioral development. In addition to the development and application of spatial models of air pollution to study pediatric allergic disease, respiratory development, and neurobehavioral outcomes, his research includes the use of personal air monitors and health sensors in epidemiologic studies. Additional research interests include the impact of naturally occurring elongated mineral fibers on respiratory and autoimmune disease in Libby, MT and other locations in the western US.
