For the past few decades, cosmological observations have painted a remarkably simple picture of our universe, one that rests on five pillars: General Relativity, the Standard Model of particle physics, Inflation, Dark Matter, and Dark Energy. Simple as it may seem, the latter three remain largely mysterious, and the former two show minor but nagging holes in need of patching. However, as we march into the era of precision cosmology, swamped by data of unprecedented volume and fidelity, there is a genuine chance that some of these mysteries can be unveiled, and many more questions unearthed in their place.
Precision data, however, demands precision techniques, and we must find ways to orient ourselves before we lose our bearings and drown in it. This is where Effective Field Theories (EFTs) earns its keep. It provides guardrails that encapsulate the relevant features of fundamental physics under controlled assumptions, and with that, it lets us pin down the unique signatures that new physics would leave in the cosmos and perform a targeted surgery to locate them with designed statistics in hand. Using EFT as both a theoretical lens and a computational engine, I work to understand the phenomenology of the universe from its earliest seconds to its latest epochs and probe fundamental physics from statistics of the large-scale structure and the cosmic microwave background. Over the past few years, this has drawn me into questions about the symmetries and statistics of the primordial universe, and into the theoretical foundations that underpin our ability to answer them at all.
