After receiving a Ph.D in theoretical philosophy from Stockholm University 1993 I was lecturer in theoretical philosophy at Linköping University 1995-2001, after which I moved to Uppsala University, where I became full professor 2008. My research interests are epistemology, philosophy of science and in particular philosophy of physics. I have extensively taught philosophy of science also at Karolinska Institute, Stockholm, Royal University of Technology in Stockholm and Swedish University for Agricultural Sciences in Uppsala.
