Applications in Physical Sciences
My research is aimed at understanding how climate influences the spatial patterns and temporal variability in ecosystems. I am especially interested in those processes that can feed back on the physical climate system, for example through atmospheric greenhouse gases. For this reason, most of my work has focused on biogeochemical cycles in the ocean. However, I am also working at the interface between thermal physiology and climate to understand patterns of biodiversity and species responses to climate change. Most of my research combines large-scale datasets and numerical models of the ocean and its biogeochemical cycles to determine global patterns and rates of ocean processes and their sensitivities to climate.
Currently, I am pursuing three fundamental and related questions in this area:
- How do climate forcing and ecosystem feedbacks act to regulate the marine nitrogen cycle?
- How does climate influence the oxygenation of the ocean?
- Why are the nutrient ratios of the ocean and its plankton so similar?
A unifying theme in all these questions is the interaction between ocean circulation and biology, and these overarching questions, while distinct, are beginning to blend in very exciting ways.
