Background
- More than 25 years of experience in applied physical oceanography / limnology, computer software development, and environmental consulting.
- Recently involved in industry/government-funded research of pit lake physics and chemistry aimed at improving our understanding of the mechanisms influencing circulation and stability.

Technical Expertise
- Physical limnology and oceanography;
- Computer programming, graphics, and software development;
- Environmental data analysis and presentation; and
- Development and application of numerical computer models for:
- Three-dimensional hydrodynamics and lake / ocean circulation;
- Tsunami generation and propagation;
- Submarine effluent discharge, transport, and dispersion;
- Surface oil spill dispersion and environmental impact;
- Pit lake stability and geochemistry;
- Sediment transport, bottom deposition and resuspension;
- Submarine tailings disposal;
- Wave-induced sediment resuspension;
- Well cuttings dispersion and deposition; and
- Produced water dispersion and dilution.

Selected Projects
- Development of a numerical model of produced water dilution for the off-shore petroleum industry with application to the Hibernia and Terra Nova well sites.
- Application of a numerical, three-dimensional hydrodynamic and pollutant dispersion model to near- and far-field dilution of submarine sewage disposal for the Victoria, BC Capital Regional District.
- Development of a numerical model of well cuttings dispersion and deposition for the off-shore petroleum industry, with application to proposed well sites at Lewis Hill, Orphan Basin, and the Laurentian sub-basin.
- Development of a coupled physical–geochemical speciation model for mine pit lakes with application to Island Copper, Selbaie, Golden Sunlight, and Equity pit lakes.
- Development of a numerical three-dimensional hydrodynamic model, with application to predicting ocean and lake circulation, dissolved contaminant dispersion, and sediment transport at numerous sites around the world.
