Interests

I am an Associate Professor in the Particle/Astrophysics Group at Case Western Reserve University. I am a theoretical cosmologist with interests in a wide range of topics, including: Developing models of the Early Universe, Inflation, Non-Gaussianities and Initial Conditions, Braneworlds and extra dimensions. More recently my research has focused on explanations of the late time acceleration of the Universe, through developing models of Dark Energy, and Modified Gravity, and addressing some of the challenges posed by the Cosmological Constant Problem.

Some highlights are:

I previously held the position of Distinguished Research Fellow in the Cosmology group of the Perimeter Institute for Theoretical Physics. Before that, I was a Postdoctoral Research Associate at the Physics Department of Princeton University. I received my PhD in Cosmology from the University of Cambridge, DAMTPGonville & Caius College in 2003. I graduated fromJesus CollegeOxford University in 1999.
