Research interests:

Mathematical logic, mainly the model theory and proof theory of axiomatic theories of arithmetic, ranging from bounded arithmetic to moderately strong subsystems of second-order arithmetic. I have also done some propositional proof complexity, some finite model theory (long ago!), and have a general interest in connections between logic and the theory of computation. I am one of the co-organizers of a seminar on these and other topics in logic.
