Dr. Linsey Marr is a University Distinguished Professor and 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.  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 nano materials and viral aerosols such as 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 COVID-19, 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.

Marr helped lead the charge to correct misinformation about COVID-19 transmission and is now considered one of the world’s leading experts on airborne transmission of viruses.
