Research
My interests center mainly on the interface between cosmology and particle physics. I have very strong interests in the quantum mechanics/field theory involved in inflationary cosmologies. This has led me to spending a great deal of time developing a formalism that can be used to describe quantum fields in non-equilibrium environments, such as occur during and immediately after an inflationary phase. This formalism has also had very interesting applications to the so-called Dark Energy problem.
I am currently involved in trying to understand how current and future measurements of the Cosmic Microwave Background Radiation could detect effects coming from Planck-Scale physics, as well as constructing models that describe the so-called Dark Energy component of the Universe.
