A new class of cosmic inflation models

The early universe is used as a theoretical laboratory for studying fundamental physics, the laws of gravity and quantum mechanical aspects of matter under extreme conditions. We study models of cosmic inflation in the early universe and dark energy in the late universe and their possible realizations in quantum field theory and string theory models. Our recent research focuses on models of high-scale inflation which produce an observable signal of gravitational waves in the cosmic microwave background.
