Barbara J. Turpin

Barbara J. Turpin, PhD, is a Professor and Director of Graduate Studies in the Department of Environmental Sciences and Engineering at the UNC Gillings School of Global Public Health. She specializes in aerosol science, atmospheric chemistry, and environmental engineering, with a focus on linking air pollution emissions to human exposure risks. Her research integrates laboratory experiments, chemical modeling, and field studies to advance public health protection strategies.

Dr. Turpin holds a BS from the California Institute of Technology and a PhD from OGI at Oregon Health and Science University. Her work has contributed to understanding organic particulate formation, indoor-outdoor air pollution dynamics, and the health impacts of PM2.5. She currently serves on the EPA’s Clean Air Scientific Advisory Committee (CASAC) and is an Associate Editor of Environmental Science and Technology.

Her research highlights include studies on aerosol chemistry in clouds, PM2.5 exposure disparities, and regulatory model development. Key awards include the Haagen-Smit Prize (2009) and AAAS Fellowship (2011). She actively advises on EPA air quality standards and collaborates with faculty in atmospheric chemistry and public health at UNC.
