I did my PhD at The University of California, San Diego (1996) with a thesis on Kant's concept of apperception. My supervisor was Henry E.Allison. My main area of research is still in the history of philosophy (1600-1800) and Kant in particular. More recently I have started to work in the fields of Military Ethics and Conceptual Engineering.
Together with Herman Cappelen and Øystein Linnebo I am a co-leader of the project "Conceptual Engineering" (funded through summer 2021 by the Norwegian Research Council) and of ConceptLab.
I am the President of the Norwegian Kant Society and Co-editor of Archiv für Geschichte der Philosophie. In 2015-16 I was group leader for the research project "Disclosing the Fabric of Reality- The Possibilty of Metaphysics in the Age of Science" (funded by Center for Advanced Study).
In 2017-2018 I was Vice President of the Norwegian Academy of Science and Letters and have served on a number of boards at the University of Oslo, as Head of Department and Dean of Research. I have also been engaged in external councils and boards:
The Norwegian Press Complaints Commission (2002- 2017); from 2012 as Head of the Ethical Council for the Defence sector (https://forsvarsetikk.no) which deals with ethical challenges in the defence sector.
From August 2018 I will be on leave from my position at IFIKK to serve as Scientific Director at CAS (https://cas.oslo.no).
From May 2019 I serve as the Head of the Portfolio Board for Social science and Humanities at the Research Council of Norway (https://www.forskningsradet.no/en/about-the-research-council/eng-oppgaver-og-organisering/portefoljestyrer/)
