Christian's philosophical interests most prominently include foundational issues in physics, particularly in classical general relativity and quantum gravity. Of course, he also gets excited about the implications of philosophy of physicsfor general philosophy of science and metaphysics. More specifically, he enjoys thinking about issues such as space and time, persistence, laws of nature, determinism, and causation.

Franz works on logic and metaphysics at Arché Research Centre, University of St Andrews, and at the Institute for Logic, Language and Computation (ILLC) at the University of Amsterdam. In the past he's been doing more or less the same at the University of Aberdeen UK, at the Institute for Advanced Study, University of Notre Dame IN-USA, at the Sorbonne-Ecole Normale Supérieure in Paris, at the University of Italian Switzerland, at the Universities of Padua, Venice, and Milan-San Raffaele in Italy. He has written a number of books and papers on topics ranging from modal metaphysics to non-mainstream metaontology, non-classical logic, non-standard computation, and almost anything deviant in theoretical philosophy. He loves logical paradoxes, impossible worlds, nonexistent objects, and philosophers who don't take themselves too seriously.
