Professor A Berera
My research areas are in Quantum Field Theory and Statistical Physics. My primary research interests are in early universe cosmology theory. I also have research interest in turbulence. My interests in cosmology have been focused on developing a more complete description of the early phases of the Big-Bang through my model called warm inflation, which I created in the mid-90s. My work in this direction involves particle physics and nonequilibrium quantum field theory.
In the past few years I have taught courses in Quantum and Statistical Physics and Quantum Field Theory.
