Research Interests
My work spans a range of scientific research topics from the global (such as climate and earth system modeling and the effects of climate varaibility and change on marine ecosystems and biogeochemical cycles) to the local (such as biogeochemical processes and impacts of eutrophication on coastal ecosystems). I combine a variety of chemical fingerprinting tools with mathematical models of physical and biogeochemical processes to elucidate controls on climate variability and change, biogeochemical cycling, and marine ecological functioning. I also collaborate on a variety of projects assessing climate change impacts.Current Projects
I am leader of GFDL's Biogeochemistry, Ecosystems, and Climate Group
Ocean Biogeochemical Model development - For the last decade, I have been working to develop models of global ocean biogeochemical cycling to be incorporated into GFDL's global models for earth system reanalysis and projection.
Earth System Modeling for fully coupled carbon-climate models through representation of the terrestrial and ocean biosphere.Marine ecosystem model development for mechanistic representation of phytoplankton physiology and trophic interactions (collaboration with Charles Stock)
Biogeochemical cycling inferred from satellites (collaborations with Jorge Sarmiento, Robbie Toggweiler and Burke Hales)
Climate impacts on:
- Human Labor Capacity
- Global Coral Reefs (collaboration with Mark Eakin and Simon Donner)
- Global fisheries (collaborations with Villy Christensen and William Cheung)
- The California Current Large Marine Ecosystem (collaboration with Ryan Rykaczewski)
- North Pacific ecosystems (collaboration with Jeff Polovina)
