I am a theoretical physicist specializing in the physics of the early universe and the scattering of elementary particles. My research seeks to uncover the fundamental laws that govern the universe by examining how basic principles of physics such as locality, unitarity, and symmetry constrain interactions of quantum fields. I employ modern computational and mathematical tools from high-energy physics to address these foundational questions. Concretely, my recent work has focused on applying scattering amplitude techniques to cosmological correlators using an approach known as the bootstrap. Additionally, I develop analytical methods for studying cosmological structure formation and extracting data from large-scale structure surveys.
