Research interestsMy research addresses problems in microbial ecology and microbial biogeochemistry generally, with specific emphases on bacterial and atmospheric trace gases. Current primary interests include dynamics of methane, carbon monoxide, hydrogen, nitric oxide and nitrous oxide. Work in my lab addresses aspects of the production and consumption of these gases by bacteria, as well as interactions between microbes and plants, and microbes and animals. Research efforts include questions related to the physiological ecology of trace-gas transforming microbes; associations between plant roots and microbes that affect gas production or consumption and the diversity and structure of trace-gas utilizing microbial communities. My research includes field studies of gas exchange in wetlands, forests, agroecosystems and nearshore marine environments. I am also exploring the role of atmospheric sources of carbon and energy in the colonization and succession of microbes on recent (0-300 yr old) lava flows. Techniques and approaches in these various studies range from applications of molecular tools, to isolation and characterization of novel microbes, to considerations of microbial contributions to trace gas budgets on a global scale.
