Academic Biography

My early work was primarily on quantum gravity. My dissertation looked at the conceptual problems which arise when attempting to "quantize" spacetime. Among these is the notorious "problem of time", whereby the time-evolution of the quantum state of the universe appears to disappear. Several papers followed from this work, exploring various aspects in more detail. I then began a critical investigation into what are arguably subjective or anthropocentric notions in physics, especially entropy, and also the notion of causality and even determinism. I continue to work on entropy, attempting to understand it in the context of gravitational physics in order to understand its extension to cosmology and the cosmological arrow of time, but my primary focus at present is on the conceptual possibility and physical plausibility of multiple time dimensions, and on the plausibility of novel relativistic models of quantum phenomena.
