Research Interests

I am a biogeochemical oceanographer who specializes in designing tracers in coastal models to ask questions about important processes in that environment. I am a research scientist at JISAO at the University of Washington, where I conduct research and sometimes have the opportunity to teach.  I look at models as tools that integrate observations and theory.  They can be used to investigate processes and mechanisms, or to try and understand future scenarios.  In addition, I explore ways to quantify and relate biological impacts with environmental variability.  My interests include:

  • The role of the coastal ocean in global biogeochemical cycles
  • How will climatic changes in sea level, winds, and stratification affect the exchange between the coastal and open ocean?
  • How are dissolved nutrients transported onto and off continental margins? Is particulate organic matter transported differently than dissolved nutrients?
  • Given the role of retention in governing spatial variability of hypoxia and probably ocean acidification as well, how will retention change in response to changing environmental conditions in the future?
  • How important is freshwater discharge to local ocean acidification events?
  • How important is the cycling of calcium carbonate in coastal regions to the surface alkalinity balance? How is that expected to change in the future?
