I am an associate professor of philosophy in the Department of Philosophy at the University of Geneva.

My current research focuses on the philosophical foundations of quantum gravity. More generally, I work in the philosophy of physics, which heavily intrudes into metaphysics and general philosophy of science. Specifically, I work on space and time, time travel, persistence, identity, laws of nature, determinism, and causation.

My Erdös Number is 3 (Erdös → Tarski → Andreka and Nemeti → me).

I am currently writing a book with Nick Huggett, which is under contract with Oxford University Press. It starts out from the recognition that in quantum theories of gravity, spacetime disappears in some sense or other and investigates the philosophical implications of a fundamentally non-spatiotemporal world, as well as how spacetime is thought to re-emerge in various of the main approaches to quantum gravity.

I am currently also working on a book with JB Manchak and Chris Smeenk, also under contract with Oxford University Press. This will be a research monograph in naturalistic philosophy of time on the possibility of time travel and time machines in modern physics, and particularly in general relativity.
