Dr. Hasnain completed her PhD from Queen’s University in Canada. Her dissertation research examines the impacts of within-species variation in traits on ecosystems, using the zooplankton genus, Daphnia and freshwater zooplankton communities in south-central Ontario as her study system. Her research employs broad inter-disciplinary approaches ranging from conducting field surveys, field and lab based experiments, developing new statistical techniques and mathematical models to answer ecological questions. Dr. Hasnain has extensive experience conducting research that addresses policy needs. Over the last ten years, she has served a data consultant, research contractor and fish habitat biologist with Fisheries and Oceans Canada, a Canadian government department managing Canada’s fisheries, oceans and freshwater resources. She has also served as an expert on the Canadian Science Secretariat, a science advisory panel to the Canadian Federal government, on using regional benchmarks of fisheries productivity to assess harm to fish and fish habitat under the Fisheries Act.
