My research focuses primarily on the CAUSAL SET THEORY (CST) approach to Quantum Gravity. Closely linked to CST is an interpretation of quantum theory called the QUANTUM MEASURE approach, which allows us to speak of quantum systems without recourse to external measurements and measuring devices, which are absent in closed systems and of course in the early universe. You can read about this approach in one of Rafael Sorkin's earliest papers on this subject. I also have a strong interest in aspects of LORENTZIAN GEOMETRY related to the role of the CAUSAL STRUCTURE.

My current research includes:
