Current Research

Understanding the impacts of human activities on freshwater ecosystems defines much of my research. Specifically, I provide credible scientific research linking anthropogenic activities such as hydroelectric dam operations and habitat alteration to effects on fish and lower trophic levels. Research projects are applied and often quite directed towards specific needs of our Fish and Fish Habitat Protection Program in support their role in administering the provisions of the Fisheries Act. I maintain a strong interest in using science to support policy development and resource management, particularly when new legislation or new technologies are involved.  I also work to maintain collaborations among academic and government researchers to meet science needs for DFO policy and management. For example, I serve on the advisory committee and am coauthoring a number of systematic literature reviews being conducted by the Canadian Centre for Evidence-Based Conservation at Carleton University on behalf of DFO, and work towards bringing the resulting scientific evidence into formal science advice to DFO management through Canadian Science Advisory Secretariat processes.
