EDUCATION

Doctor of Philosophy, Physical Oceanography, Oregon State University,
(June 2000). Pioneered new instrumentation techniques and methods (developed a fast-thermocouple sensor; acquired and analyzed the first direct measurements (i.e., fluxes and resolved spectra) of turbulent salinity microstructure) in an attempt to better understand ocean physics on the smallest scales. Identified a new source of drag and mixing on the continental shelf - hydraulic flows - and analyzed the associated energetics.

Master of Science, Civil and Environmental Engineering, Cornell University, (January 1995). My thesis "Buoyant Jets in Reversing Crossflows" combined laboratory experiments and field data to parameterize processes for simple predictive models.

Bachelor of Science, Engineering Physics, Queen's University
(Kingston, Ontario; May 1991). Dean's scholar; First Class Honours. Achieved rank between first and third in the program each year.

RELATED EXPERIENCE

Research Associate (Postdoctorial), Applied Physics Laboratory, University of Washington, June 2000-2002.

Working with Eric Kunze to investigate internal wave/topography interactions along the corrugated slope near Virginia. Active participant in the Hawaiian Ocean Mixing Experiment (with Sanford, Kunze and Lee). Research Oceanographer, Ocean Mixing Group, Oregon State University, May-September 1999. Headed the at-sea operations of microstructure profiling during the 18 day NOPP wind-driven circulation experiment on the Oregon Coast. Responsible for both the cruise preparations and the decision-making while at sea. While a Ph.D. student, I participated in the design and development of new instrumentation and field experiments during more than 10 cruises. Model Developer for Army Corps/EPA, January-May 1995. Developed a near-field sediment transport model for use with continuous dredge discharges. Adapted jet-integral and density current models with settling to predict suspended sediment concentration. A PC-based expert system allowed the user to defined discharge and ambient parameters (stratification, current, bottom slope, discharge geometry, etc.) Research Technician, Laboratory for High Temperature Superconductors, University of British Columbia, February-August 1992. Constructed and assembled a laser ablation system for producing thin-film YBaCuO high-tc superconductors. Gained experience with laser optics, computer-controlled manipulation, and high vacuums. Research Student, Queen's University (Kingston, Ontario), May-August 1990. Responsible for producing single lithium crystals for a Japanese Compton scattering experiment. Designed and built a crystal growing chamber, grew single crystals, and oriented them using forward scattering x-ray techniques. Research Assistant, Xerox Research Centre (Mississauga, Ontario), May-August 1989. Determined the feasibility of using existing Xerox ionographic printers for Magnetic Ink Character Recognition (MICR) printing. Excessive smearing of the printed characters was found to be the largest MICR obstacle. Applied many different characterization techniques to determine its cause and suggested a printing technique that reduced the problem by two orders of magnitude. Xerox obtained a United States Patent in my name for this invention.
