I am a physical oceanographer with skills in fluid mechanics including scaling, analytics, laboratory and numerical modeling. My areas of application include coastal oceanography, mesoscale meteorology and biological-physical interactions in the ocean.
My largest scholarly contributions have been to 1) understanding flow over and around topography and particularly canyons, and the resulting impacts on cross-shelf exchange. I have also made significant contributions to 2) biological-physical interactions and in particular the impact of surface processes on the timing of the phytoplankton spring bloom and 3) in collaboration with D. Steyn, I have contributed to the study of atmosphere buoyancy driven flows in the mountains. 4) Lastly, I work in an interdisciplinary oceanography group within the Department of Earth and Ocean Sciences. As a community member I have contributed in a number of fields, usually applying my modeling or analytic skills. If one can create a simple model of a phenomena so much of our intuition and understanding can be illustrated and quantified.
1) Flow over Topography in the Ocean, particularly Canyon Flows
Long Term Goal: To be able to understand the rotationally dominated flow over topography and quantitatively estimate the cross-bathymetric gradient flows and the scalar fluxes they generate.
2) Biological-physical Interactions and Modeling
Long Term Goal: Produce local models of the lower trophic-level ecology and carbon/oxygen/nitrogen cycles based on simplified (but accurate) physical models of local coastal regions. Use these models to investigate the relevant processes that determine primary productivity, carbon fluxes and acidity.
3) Buoyancy Driven Flows in the Atmosphere
General Goal: Defining and quantifying buoyancy driven flows through and on our local mountains.
