### 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.
### Publications:
