I am professor of philosophy at the Department of Philosophy, Classics, History of Art and Ideas, Faculty of Humanities, University of Oslo. My main research interests are in political and environmental philosophy, and ethics. I am the principal investigator of the five-year ERC project Dynamic Territory: A Normative Framework for Territory in the Post-Holocene, which asks how to solve conflicts of interest around land and natural resources on a global scale, when the stability and predictability of geographic, climatic and demographic factors can no longer be taken for granted. Based on that research, I have a forthcoming book entitled From Sovereignty to Guardianship: Governing Antarctica, Governing the World. There, I take Antarctic governance as an inspiration for the territorial governance of global systemic resources, but also suggest ways in which global environmental governance should go further, moving beyond state-centrism and anthropocentrism. My work so far has focused on the foundations of basic human rights and global justice (see The Right of Necessity) and the justification of territorial rights and rights over natural resources. I am the co-editor of Colonialism and Antarctica: Attitudes, Logics, and Practices (you can download it here), and Theories of Justice. I have an ongoing interest in natural law theory, the Scottish Enlightenment, and philosophical traditions beyond the Western canon. I am associate editor of the Journal of Applied Philosophy, affiliated researcher at the Norwegian Nobel Institute, and member of the steering committee of the Standing Committee of the Humanities & Social Sciences, Scientific Committee on Antarctic Research.
