I am a theoretical physicist working on string theory and what it means for the physics we can observe.
My research asks how the geometry of the extra dimensions shapes low-energy physics. I compute the masses, couplings and cosmological consequences of axions across large ensembles of explicit Calabi–Yau compactifications; I test proposed quantum-gravity constraints on effective field theories; and I develop new mathematical and computational methods for studying Calabi–Yau geometry.
Before joining the IAS, I was a postdoctoral fellow at Harvard University. I received my Ph.D. from Cornell University in 2023, advised by Liam McAllister, after an M.Sc. in applied mathematics at the University of Auckland and a B.A. in physics at Reed College.
