Celia Byrne

Celia Byrne is an Associate Professor in the Department of Preventive Medicine and Biostatistics at the Uniformed Services University of the Health Sciences (USUHS). She holds a dual appointment in the Department of Epidemiology and Biostatistics. Her academic background includes a Bachelor's in Biology from Earlham College and a PhD/Master's in Epidemiology from UCLA.

Her research focuses on environmental exposures, breast cancer epidemiology, and public health disparities. Key projects include investigating polycyclic aromatic hydrocarbons (PAHs) and breast cancer risk, environmental metal impacts on breast density, and the effects of SARS-CoV-2 on long-term health outcomes in military populations. She has led federally funded studies, such as the US Army-funded PAHs and Breast Cancer Risk project and a National Institute of Environmental Health Sciences study on metal/metalloid exposures.

Byrne’s work bridges epidemiology and biostatistics, emphasizing methodological rigor in analyzing population-level health data. Her recent studies address post-COVID-19 sequelae, vaccination impacts, and racial disparities in endocrine-disrupting chemical exposure. Collaborations include multidisciplinary teams across military and civilian institutions.

Her publications span environmental health, infectious disease epidemiology, and breast cancer research. Notable contributions include analyses of long-COVID symptoms, hybrid immunity mechanisms, and the role of acculturation in breast density among immigrant populations.
