I am an Associate Professor (formerly Reader) in the Department of Philosophy at the University of Bristol. I am also an external member of the  Munich Center for Mathematical Philosophy (LMU Munch).

My current research is principally within physics and the philosophy of physics. My main research focus is the problem of time in classical and quantum theories of gravity. Further topics of current interest include dynamical approaches to symmetry, black hole physics, analogue gravity, quantum cosmology, the arrow of time in quantum theory, and the foundations of general relativity.

I have previously worked on various topics in the epistemology and methodology of natural and social sciences.

I am keen to support the applications of students for doctoral studies relating to technically informed projects in the philosophy and foundations of physics. If you have the appropriate background and interests please contact me.
