Scientific consultant, Habitat Ecology Division, Fisheries and Oceans Canada, Bedford Institute of Oceanography

Research on the natural processes of oil-mineral aggregation and their enhancement to clean-up oil spills and mitigate environmental impacts in marine and fresh waters. This work has advanced the fundamental understanding of the ways oiled shorelines self-clean, has produced field and laboratory methods to detect and characterize oil-mineral aggregation and has helped validate clean-up methods based on the acceleration of this natural process.

May 1996 - August 2002

Scientific consultant, Marine Environmental Sciences Division, Fisheries and Oceans Canada, Bedford Institute of Oceanography

Identification of black carbon particles from combustion of wood, coal, or oil in marine sediments of Halifax Inlet. Black carbon particles are a tracer of human activity in space and time and thus a useful tool to evaluate the extent of industrial environmental impacts.

April 1995 - March 1996

Contractual manager of the Microanalysis Facility, Geological Survey of Canada Atlantic, Bedford Institute of Oceanography

The emphasis of my work has been to solve scientific problems in a variety fields (environmental geology, marine chemistry, sedimentology, mineralogy, microbiology, palaeontology, palynology, geomechanics) in diverse environments (i.e. Halifax Harbour, Arctic Ocean, the deep-sea) using novel analytical techniques. Under my supervision, the laboratory grew into a multi-user facility with state-of-the-art instruments servicing the needs of government institutions, universities and the private sector.

October 1981 - September 1983

Research Associate,Department of Oceanography, Dalhousie University
