My work focuses on learning about the physics of the early universe from cosmology. This means studying how high-energy processes in the early universe can lead to things we can measure today, and conversely how things we measure in the sky constrain the form of high-energy physics.
In particular, I have worked extensively on how the physics and symmetries of cosmic inflation constrain the ways in which it can produce observable relics like black holes, gravitational waves, and non-Gaussianity. I have studied the behavior and role of the Higgs field in the early universe, and the imprints of axions as a dark matter candidate.
