Current Research Interests
My broad research interests are related to agricultural air and water quality issues. I am particularly interested in research aimed at better understanding the surface-atmosphere exchange of energy and gases within agricultural systems.
My PhD research at the University of Guelph (Ontario, Canada) focused on mitigating methane, nitrous oxide and ammonia emissions from liquid dairy manure management systems.
My research at the University of Minnesota is focused on examining the biogeophysical and biogeochemical radiative forcings associated with conventional and alternative corn/soybean management systems. The aim is to quantify management induced differences in the radiation and energy balances; and carbon dioxide, nitrous oxide and methane exchange using long-term field-scale measurements. Modeling will be used to scale-up to the region, and examine feedback effects. The ultimate goal is to determine how the widespread adoption of alternative management systems could affect the regional climate.
