Statement: My research interests are focused on understanding the influence of open biomass burning on the chemistry and composition of the atmosphere. Several aspects of biomass burning are investigated in my research program, including smoke characterization, emission inventories, smoke plume dynamics, and the transport and air quality impact of emissions. Ongoing studies in these areas include: 1) the development of satellite based wildfire emission inventories for the western United States, 2) airborne and ground based experiments for the validation of smoke transport models, 3) development of a prototype fire emission – smoke dispersion forecasting system, and 4) laboratory and field experiments characterizing the gas and aerosol emissions from prescribed burning. As a U.S. Forest Service scientist, my emission inventory research has focused on biomass burning that is most pertinent to air quality and land management in the United States.
