Brief synopsis of current research:
We develop new sonar techniques for detecting and surveying fish and zooplankton in rivers, lakes, and shallow coastal areas. In one project we were able to detect migratory salmon in the Strait of Georgia at horizontal distances up to 7.5 km. We have also developed sonars for detection of herring schools in shallow waters (<12 m deep) which we have tested in the Gulf of St. Lawrence and near Copenhagen, Denmark.

I began a career as an oceanographer because I feel that properly understanding the ocean is very important to our world and to Canada. Many aspects of Canadian life revolve around the oceans and our exploitation of its fish and zooplankton resources. However, as recent declines in fish stocks demonstrate, we must consider these resources as finite and do our best to manage these resources. Even now, our understanding of the oceans and marine life is limited, and I am motivated to develop new tools to help learn more about the oceans.
