### Research interests:

Mathematical logic, mainly axiomatic theories of arithmetic (especially weak ones). 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.
### Publications:

You can find a list here, with most of the items available for download.
### Teaching (in Polish):

Materia³y zwi±zane z zajêciami, które prowadzê b±d¼ prowadzi³em, mo¿na czasem znale¼æ tutaj.
