Research Program My research program has two components. One component is collaborative work with Harold van Es (with input from other CSS personnel and staff of the Northeast Regional Climate Center) with the goal of developing a decision tool to improve soil nitrogen management for maize production in New York State. The other component involves the GLOBE program (GLOBE: Global Learning and Observations to Benefit the Environment) jointly funded by NASA and NSF. GLOBE is a science education program for K-12 students in schools around the world. I am working with a team to provide students with simple computer models that enhance their understanding of the linkages among the components of the Earth’s environment.
