Research Interests

For the past 30 years Dr. Stern’s research has involved the study of environmental pathways of contaminants including their delivery, transport, and elimination from Arctic marine and freshwater aquatic ecosystems. His current research focuses in on the development of oil detection and remediation technologies, impacts and fate of oil spills in Arctic marine environments. Among others, Dr. Stern currently co-leads the Genome Canada projects entitled “GENICE - Microbial Genomics for Oil Spill Preparedness In Canada’s Arctic Marine Environment (2016-2022)” and "GENICE II: Reimagining monitored natural attenuation as an oil spill response tool in the Arctic. He is the Director of the new state-of- the-art contaminant and petroleomic facility in CEOS (PETRL; Petroleum EnvironmenTal Research Laboratory) and is the Chair of Churchill Marine Observatory Board of Directors. In 2016 Dr. Stern was awarded Governor General of Canada’s Polar Medal. This medal celebrates Canada’s northern heritage and recognizes persons who render extraordinary services in the polar regions and in Canada’s North.
