We have quantified and characterized bioaerosols in indoor swimming
pools, hospital showers, metalworking factories, and the outdoors
by both culture-dependent and genome-enabled assays. The goal of many
of these studies is to not only characterize potential pathogens in
air, but also to test engineered mitigation strategies. We are now
interested in pursuing problems
with airborne microbes, including bacterial pathogens and fungal spores,
in households and agricultural-related indoor environments.
This area of study in our lab is currently sponsored by the Sloan
Foundation (Microbiology of the Built Environment) to study weatherization
efforts for older homes in the Northeast. Graduate students Mytien Nguyen and Catherine Sprito are working on this effort.
