Erika Garcia is an Assistant Professor in the Division of Environmental Health of the Department of Preventive Medicine at the Keck School of Medicine of USC. She is an environmental epidemiologist whose research focuses on the role of airborne environmental contaminants in the development of human disease and applies both traditional epidemiologic as well as advanced causal inference methodologies. She has published studies conducted in both occupational and community exposure settings. Her early research involved examination of the healthy worker survivor effect and application of g-methods in cancer studies of autoworkers exposed to metalworking fluids. More recently, her research has focused on the effects of early-life air pollution exposure on pediatric respiratory and metabolic health outcomes, including new-onset asthma, lung function, and childhood obesity. As part of these studies, she uses causal inference methods to estimate effects of policy-relevant air pollution interventions. Dr. Garcia received a PhD and MPH in Environmental Health Sciences from the University of California, Berkeley.
