Theoretical physicist, KICP Fellow at the University of Chicago

I am a theoretical physicist working on cosmology and particle physics, and in particular on the physics of the early universe.

I joined the Kavli Institute for Cosmological Physics at the University of Chicago in September 2025. Before that, I spent three years as a postdoc at the University of Florida’s Institute for Fundamental Theory. I received my Ph.D. in physics from the University of Minnesota in 2022, where I worked with Keith Olive on no-scale supergravity, inflation, and dark matter.

I studied physics with astronomy at the University of Southampton, earning a BSc and an MPhys. During the MPhys, I spent a year doing research with Belinda Wilkes at the Harvard-Smithsonian Center for Astrophysics.

Mentoring and teaching

Cosmological particle production

With Jingyuan Wang and Rocky Kolb, I worked on gravitational particle production in multifield inflation and its implications for the origin of dark matter. Read the paper

Gravitational waves from cosmic strings

Work with Christos Litos and collaborators investigates gravitational waves from long strings and loops. Read the paper

Machine-learned symmetries

I worked with graduate students Roy Forestano, Alex Roman, and Eyup Unlu on work relating machine learning to continuous symmetries and Lie algebra structure. The collaboration produced four papers in 2023, one in Machine Learning: Science and Technology and three in Physics Letters B.

Teaching

At the University of Florida, I was a guest instructor for undergraduate Classical Mechanics and the graduate Standard Model course. At the University of Minnesota, I was a teaching assistant for introductory physics, undergraduate Quantum Mechanics, and graduate Advanced Quantum Mechanics. I received the Outstanding Teaching Assistant Award in 2020.
