The North American and Arctic Defence and Security Network (NAADSN) addresses three core policy challenges – the Defence role in the Arctic, NORAD modernization and the future of North American defence, and the evolving role of major powers in global strategic competition – and their many intersection points by: -conducting leading-edge research with students, emerging scholars, and Northern stakeholders/rightsholders that tests core assumptions and prompts policy innovation -convening conferences, workshops, and symposia that bring together diverse stakeholders on issues of core interest to the Defence Team -educating the next generation of policy thinkers and analysts Researchers work in multi-/inter-disciplinary research clusters organized across three scales (circumpolar and international security, defence of North America, and defence of Canada) and specific topic areas. Our network structure is deliberately elastic so that we can respond efficiently to emerging issues and mobilize small expert teams to present relevant and timely advice to the Defence Team.
