Peter is a specialist in geomatics and cartography and received his Ph.D at Carleton University. His research addresses questions related to the use of geographic information with a particular focus on supporting interoperability. Semantic interoperability, the ability to effectively share meaning across knowledge systems, is at the core of his research. These research themes are highly relevant to his focus on community-based research and consideration of the links between Western scientific and Indigenous Knowledge. Since 2006 his work has focused on working with and addressing priority issues of Inuit and other Indigenous Peoples of the Arctic (i.e. Gwich’in, Yup’ik, Saami). This includes extensive experience working directly with Indigenous communities in a co-production model for the establishment of community-based expertise, capacity, and information infrastructure. Peter is the Associate Director of the Geomatics and Cartographic Research Centre (GCRC), which focuses on the application of geographic information processing and management to the analysis of socioeconomic issues of interest to society at a variety of scales. Peter is also a research scientist at the National Snow and Ice Data Center, University of Colorado, where he leads the Exchange for Local Observations and Knowledge of the Arctic (ELOKA) and other projects. For almost two decades, he has been active in the coordination of international polar data activities and currently chairs the international Arctic Data Committee, and acts as Technical Co-Lead of the Canadian Consortium for Arctic Data Interoperability, the co-chair of the U.S. Interagency Arctic Research Policy Committee, and the Canadian representative to the Standing Committee on Antarctic Data Management.
