My research interests include the exchanges of carbon dioxide (CO2) and water vapor in key agricultural and natural ecosystems. My work has quantified the seasonal and inter-annual variability of net ecosystem CO2 exchange and evapotranspiration, in irrigated and rain-fed maize-soybean cropping systems. I regularly collaborate with scientists in other disciplines at UNL and other institutions, to advance our knowledge of the carbon and water cycles and global climate change.
My appointment is 100% within SNR: 60% research and 40% scholarly service. I conduct research on the exchange of carbon dioxide, water vapor, and energy as part of the Carbon Sequestration Program (CSP) at three research sites at the Agricultural Research and Development Center in Mead, Nebraska.
