I am interested in tropical terrestrial biogeochemical cycling, with a particular emphasis on nitrogen cycling related to global change. My research focuses on the way nutrient additions affect the fate of nitrogen, and the potential for deleterious losses to the atmosphere. I am part of a multi-institution effort to understand the environmental consequences of increased fertilizer use in Sub-Saharan Africa. I am also a part of the NSF Luquillo Critical Zone Observatory, where I am interested in examining nitrogen losses with an emphasis on understanding controls on the most poorly constrained aspect of the nitrogen cycle, dinitrogen, in order to better inform nitrogen budgets.
