I am working as an Interdisciplinary Postdoctoral Researcher at the Perimeter Institute for Theoretical Physics in Waterloo, Ontario, Canada, focussing on classical and quantum aspects of general relativity.

Before joining PI in January 2012 I was a postdoctoral fellow at the Albert Einstein Institute in Potsdam, Germany. Until late 2010 I did my Ph.D. in the Relativity & Gravitation Group at DAMTP, Cambridge, under the supervision of Prof. Gary Gibbons. For more information see my CV .

I am interested in the interplay between various non-perturbative approaches to quantum gravity, which often involve some form of discrete structures, and low-energy physics. At the moment I am focussing on minisuperspace models for quantum cosmology, the role of Lorentz invariance in canonical gravity, and formulations of gravity as constrained "BF theory". More on my research pages.
