Österblom has a PhD in Marine Ecology from the Department of Systems Ecology at Stockholm University, and a Master’s Degree in Behavioural Ecology from the Department of Zoology at Uppsala University.
He is interested in ocean ecosystems and ways to improve stewardship of marine resources. Starting as a seabird ecologist, with a particular interest in social interactions between alcids, he has worked on understanding how the Baltic Sea is managed, how international collaboration emerged to address non-compliance in Southern Ocean fisheries, and how transnational corporations shape the present and future ocean. Ongoing work is focusing on the speed and role of science in society, global cooperation and altruism, and understanding cascading industry effects from novel sustainability approaches. He has worked at the Swedish Museum of Natural History, and as Special Advisor to the Swedish Government in the Secretariat for the Environmental Advisory Council.
