He is also interested in (related) issues in philosophical logic, the philosophy of language and the philosophy of mind, as well as in (the history of) moral and political philosophy. After completing his PhD dissertation on the metaphysics of modality at the University of Geneva, he spent some time in the UK (Oxford and Glasgow) as an SNF-funded postdoc working on causation and grounding, and he is now pursuing, as a member of the Geneva Symmetry Group, a research project at the frontier between metaphysics and the philosophy of physics.

Kathrin Koslicki
Full Professor, University of Neuchátel
