Aaron Hillman

Aaron Hillman is a Dubridge Postdoctoral Scholar Research Associate in Theoretical Physics at the California Institute of Technology (Caltech), affiliated with the Division of Physics, Mathematics, and Astronomy. His research focuses on foundational questions in theoretical physics, particularly in string theory, quantum gravity, cosmology, and scattering amplitudes. He explores topics such as S-matrix principles, bootstrap methods, and holographic dualities. His work bridges mathematical rigor with physical intuition, addressing challenges in UV/IR divergence structures, cosmological correlators, and phenomenological implications of string models.

His research interests span a spectrum of advanced theoretical topics, including:

• Bootstrap approaches to string scattering and conformal field theories
• Quantum gravity in de Sitter and asymptotically flat spacetimes
• Mathematical structures of Feynman integrals and polytopes
• Emergent time and cosmological dynamics
• Phenomenological models linking string theory to particle physics

Hillman's recent publications highlight a focus on precision methods for scattering amplitudes, cosmological wavefunctions, and the interplay between UV/IR divergences. His work often combines numerical bootstrap techniques with analytical approaches to uncover universal principles governing physical systems. While no awards are explicitly listed, his research trajectory reflects active engagement with cutting-edge theoretical questions.
