I'm a researcher in logic at the department of philosophy, linguistics and theory of science of the University of Gothenburg.
I did my PhD in Mathematics at the University of Birmingham and Chalmers University of Technology in 2004 with a thesis on mathematical logic and models of Peano's arithmetic, under supervision of Richard W. Kaye. After which I worked as an associate professor at the Mid Sweden University in Sundsvall before starting at the University of Gothenburg in 2006.
