Academic Interests

My main research interests are in the philosophies of logic and mathematics, metaphysics and the philosophy of language. I am particularly interested in questions concerning ontology, individuation, essence, reference (especially to abstract objects), necessity and knowledge of necessary truths. My approach to these questions is broadly Fregean in that I relate them to questions in philosophical logic and the philosophy of language. 

Higher education and employment history

I took up my current position as Professor of Philosophy at the University of Oslo in August 2012. Before that, I was a Professorial Fellow at the Northern Institute of Philosophy, Aberdeen, a Professor in the Department of Philosophy at Birkbeck College (January 2010 - July 2012), and a Lecturer and then Reader in Philosophy at the University of Bristol. I have also held Research Fellowships at the Universities of Oxford and Oslo. I obtained a PhD from the Department of Philosophy at Harvard University in 2002 and an MA in Mathematics at the University of Oslo in 1996.
