Global

The evolution of global datasets derived from remote sensing techniques and the great expansion of existing datasets have allowed us to generate highly interconnected biogeochemical models. Our lab is focusing on scouring numerous databases with valuable geochemical data and collating these data to help inform current models, refine our understanding of geochemical cycles, or explore new hypotheses. This work is perhaps some of the most interdisciplinary in our lab, which includes geographical, geological, biological, and chemical techniques. On a given day a researcher can switch between the haversine formula and microbial kinetics. Previous work in this research arm has involved describing the sulfur cycle in marine sediments. Currently we are investigating the global nitrogen cycle and are particularly interested in the emission of nitrous oxide.
