I work in logic and the philosophy of mathematics. I am an associate professor of philosophy and mathematics at the University of Illinois at Urbana-Champaign.

During the 2014-15 academic year I am a EURIAS fellow at the Mediterranean Institute of Advanced Research (IMéRA) in Marseille, France.

I am also an editor of the Review of Symbolic Logic.

My CV may be found here.

Voici mon CV français.
