Research Interests
Marr's group applies a quantitative approach to track emissions, transport, transformation, and fate of atmospheric pollutants. Methods include laboratory and field experiments, data analysis, and computer modeling. The outcome of her group's research is an improved ability to monitor, predict, and control air quality, with the ultimate effect of optimizing air pollution management strategies and thus improving human health and welfare. Current research projects involve (1) assessing the environmental impacts of engineered nanoparticles, (2) developing new technologies for detecting airborne nanoparticles, (3) determining the viability of microbes in nanoscale and microscale aerosols, and (4) determining the interactions of nanoscale particles with emissions of semi-volatile organic compounds from building materials.
