Ed Avol is Professor of Clinical Preventive Medicine, with expertise in exposure assessment and acute/chronic respiratory and cardiovascular effects of airborne pollutants in populations at risk (including children, athletes, and subjects with compromised lung function). He was the Deputy Director of the Children's Health Study and is a key investigator in multiple ongoing investigations of the effects of environmental exposures on human health. He is the co-Director of the Exposure Assessment and GIS Facility Core in the NIEHS-supported Southern California Environmental Health Sciences Center, co-Director of the Exposure Assessment and Modeling Core in the NIEHS/EPA-supported Children's Environmental Health Center, and is the principal investigator on several NIH and regionally funded studies to assess the association of air pollution with children?s respiratory and cardiovascular health. Professor Avol is also actively involved in the centers’ community outreach efforts, particularly with regard to the health and air quality impacts of the Los Angeles/Long Beach Port expansions.
