Research Interests:

Research interests include utilizing dynamical models and numerical simulations to learn about the dynamics of coastal ocean currents:

• Geophysical Fluid Dynamics
• California Undercurrent
• Nonlinear Upwelling
• Equator-crossing currents
• Axisymmetric Rotating Gravity Currents

Education:

Ph.D., Dept. of Mathematical Sciences University of Alberta, 2002
M.S., Dept. of Mathematics and Statistics McGill University, 1997
B.S., Honours Mathematical Physics; Co-op  Simon Fraser University, 1995

Professional Appointments:

Assistant Professor, Mathematics Departmentt, California Polytechnic
University, San Luis Obispo, 2005 - present

Postdoctoral Research Associate, College of Oceanic and Atmospheric Sciences, Oregon State University, 2002-2005

Research Projects:

• California Undercurrent
• Nonlinear Upwelling. This research has been accepted for publication in the Journal of Physical Oceanography.
• Equator-crossing currents. This constituted my Ph.D. thesis research. Research results were been presented at the IUTAM symposium on Advances in Mathematical Modelling of Atmosphere and Ocean Dynamics, and published in the Canadian Applied Mathematics Quarterly, the Journal of Physical Oceanography and the Journal of Geophysical Research.
• Axisymmetric rotating gravity currents. This research has been published in the Journal of Fluid Mechanics. Forced disturbances in a zero vorticity gradient environment. This was my M.Sc. thesis research, and has been published in the Journal of the Atmospheric Sciences.
