We examine multiple aspects of the soil-plant-atmosphere system for exchange of nitrogen, sulfur, chlorine, bromine and iodine. The volatile forms of these gases are involved in all of the most important climate change issues, from global warming to global cooling to ozone formation and loss. The lab is focused on examining the atmospheric and environmental impacts of changing the way we manage land (e.g. the impact of increased demand for biofuels). We utilize growth chamber and greenhouse grown plants to identify the parameters that are most important in controlling the emissions of these important trace gases. An understanding of the enzymatic and genetic drivers that produce the emissions of interest is also required.
We have developed the methodology to pursue an intensive study of microbial diversity within forested soils and how changes in this community affects fluxes of trace gases to the atmosphere. We have identified differences in thermal adaptation between Arabidopsis ecotypes in the secondary metabolism process that generates methyl halides.
