Research Interests
My research interests concern multiple aspects at the interface of quantum theory and gravitational physics and in the foundations of quantum physics.
At the moment, my focus lies on a reconstruction of quantum theory (state spaces) from simple and intuitive information theoretic principles and operational arguments which solely concern the relation between an observer and an observed system.
A further current research interest concerns the description of spacetime geometry in terms of (quantum) information and probability measurements to which observers within it have access.
Moreover, I am working on a consistent canonial formalism for the quantization of systems with time varying discretization and therefore time varying numbers of degrees of freedom. Such systems arise naturally in discrete gravity models underlying various approaches to quantum gravity. Thus far, a consistent canonical description of such systems in the quantum theory has been lacking. This work relies on a classical formalism developed with Bianca Dittrich.
