Dr. Marr is the Charles P. Lunsford Professor of Civil and Environmental Engineering at Virginia Tech. She holds a B.S. in Engineering Science from Harvard College and a Ph.D. in Civil and Environmental Engineering from the University of California at Berkeley. She leads the Applied Interdisciplinary Research in Air (AIR2) laboratory and teaches courses on air pollution and environmental engineering. She is a Fellow of the International Society of Indoor Air Quality and Climate and has served on a National Academies of Sciences, Engineering, and Medicine committee on Grand Challenges in Environmental Engineering and Science in the 21st Century. Dr. Marr’s research group studies the emissions, transformation, transport, and fate of pollutants in indoor and outdoor air.
She is especially interested in emerging or non-traditional aerosols such as engineered nanomaterials and viral pathogens and how they can be physically and chemically transformed in the environment. Her research on the airborne transmission of infectious disease has focused on influenza, Ebola virus disease, and Legionnaire’s disease. She collaborates broadly with others to understand how changes at the microscopic to global scale affect public and environmental health.
