Hayden Lee

Hayden Lee is an Assistant Professor in the Department of Physics and Astronomy at the University of Pennsylvania. His research focuses on cosmology and high-energy theory, with an emphasis on the physics of the early universe and the scattering of elementary particles. Lee employs computational and mathematical tools from high-energy physics to explore foundational questions in quantum field interactions. His work includes applying scattering amplitude techniques to cosmological correlators and developing analytical methods for studying cosmological structure formation. He is affiliated with the School of Arts & Sciences and can be contacted at haydenhl@sas.upenn.edu or via his profile page.

Hayden Lee is a researcher in Cosmology and Particle Physics, focusing on the theoretical foundations of cosmological models and their observational implications. His work explores the interplay between quantum field theory and cosmological perturbations, particularly in the context of inflation and primordial non-Gaussianity. Lee's research includes the development of the cosmological bootstrap approach, which leverages symmetries and factorization to compute inflationary correlators. He also investigates the role of singularities, analyticity, and differential equations in understanding the early universe. His publications address topics such as galaxy bispectra, CMB×LSS power spectra, and cosmological double-copy relations, contributing to the broader understanding of cosmic structure formation and high-scale inflation.
