Joshua is a postdoctoral researcher with the Exchange for Local Observations and Knowledge of the Arctic, focusing on Indigenous data and storytelling. These projects also co-produce knowledges that Indigenous communities employ in documenting and sharing their history, lifeways, and languages, along with information about climate change and ecological changes in their areas.
