Welcome to my research page.Chalk Smile

I am a theoretical physicist with interests in the philosophy of science working on spacetime theory and quantum gravity. I am currently a Research Associate in the Philosophy Department at the University of Bristol.

I am happy to chat with students, researchers, and anyone who is keenly motivated by the inner workings of our Universe. To email me, go to Contact.

Research Interests

I am interested in the most fundamental of questions about the nature and origin of the Universe. Of these, I find those related to our knowledge of the properties of things in space and time to be most compelling because they are central to our understanding of some of the biggest open questions in physics. Particularly puzzling is how  two of our most revolutionary theories of physics — Einstein’s theory of General Relativity and Quantum Theory — can coexist in one simple framework that one might call Quantum Gravity. This hundred-year-old problem has proved to be particularly elusive, and may involve a complete rethinking of the nature of reality.

In my research, I have focused on two important aspects of quantum gravity: the question of what notion of time should be retained in such a theory and what role units; i.e., quantities with a built-in scale; should play in the theory. I am currently developing these ideas at the Philosophy Department at the University of Bristol where I teach and do research as a postdoc.
