Quantum Cosmology and Quantum Foundations

Illustration of a wormhole

The overarching concern of our research program is the form and character of formulations of quantum theory general enough both to pose quantum questions in space and time (as opposed to merely at a moment of time), and to encompass a quantum theory of spacetime — quantum gravity. These issues are explored through applying quantum mechanics to the universe as whole as described by quantum mechanical models of gravity, a field called quantum cosmology, and by studying how quantum mechanics itself can be used to describe closed systems with no external observers.
