About Graham Leigh

I am associate professor (docent) in Logic and Head of Research at FLoV. My research interests concern the interface between the three facets of logic: mathematical, philosophical and computational logic. I have worked in proof theory, theories of truth, non-classical logics, computational content of logics, and modal logic.

For information about our research seminar in logic and activities of our group see our external webpage.

My interview with the Wallenberg Foundation: Reflecting on truth with the help of logic.
