About me

Research

Extreme astrophysical environments provide rare opportunities to test the fundamental laws of nature under conditions that go beyond the limitations of terrestrial laboratories. In my research, I develop the theory and phenomenology of well-motivated microphysical models. I then use these to identify and -- when relevant -- search for observational signals from new fundamental physics that may be imprinted on astronomical or cosmological observables. 

In the past, much of my research have focused on the cosmology of string compactifications, the theory of inflation, and astronomical signals from axions.
