Personal profile
Research areas
Lin researches the international politics of the Arctic. She focuses on the politics of a dramatically changing Arctic climate, including the international knowledge production on melting ice. Lin also researches the security politics of Denmark-Greenland-Faroe Islands as well as US Arctic policy.
Current research
Lin’s PhD project researches the interplay of international politics and climate change research in the Arctic region. She focuses on different types of melting ice in the Arctic, how this dramatic change in the Arctic climate is researched and understood, and what it means for international politics. By focusing on three types of melting ice in the Arctic – sea ice, permafrost and the Greenland ice sheet – the project explores how we know what we know about Arctic climate change, and what it means for international politics in the Arctic and beyond.
In addition, Lin focuses on security and defence politics in the Arctic and North Atlantic. She has co-authored a number of policy reports and book chapters focusing on the changing security politics of the Arctic, the increasing focus of the US on the Arctic, renewed deterrence logics in the region, and the consequences of this for the complicated relations of the ‘Rigsfællesskab’.
