Research Interests

I work on inflationary model building, using different approaches to uncover the particle content of the very early universe. My research pairs up the focus on specific classes of models, such as axion inflation, with the more agnostic approach afforded by the use of effective field theory techniques. I complement these efforts with the exploration of the signatures associated to the inflationary field content, with a special focus on primordial gravitational waves. The energies at play during inflation, likely many orders of magnitude above those accessible via particle colliders, make cosmological probes of inflation the best available portal onto high energy physics, an ideal testing bed for (beyond) Standard Model physics and, possibly, quantum gravity.
