"What in the world am I doing to my lungs, and what can I do about it?" I've often wondered while choking on vehicle fumes during a run along the Charles River or a ride up Mt. Tamalpais. Air pollution deleteriously affects not only human health, but also visibility, global climate, ecosystems, agriculture, and cultural treasures. Our research group in Air Quality Engineering at Virginia Tech studies emissions to the atmosphere and their transport and transformation through field, laboratory, and modeling experiments.


Post-doc AJ uses our particle measuring equipment, including a scanning mobility particle sizer and aerosol particle sizer, to characterize viruses that he aerosolizes into a chamber.

Ph.D. student Andrea Tiwari reacts fullerenes with ozone in a smog chamber to determine whether they are readily oxidized in the atmosphere, and if so, what the products and their effects might be.

M.S. students Bardia and Peeyush are measuring pollutant emissions from construction equipment in order to develop improved methods to estimate the carbon footprint of a construction project.
