I am a theoretical physicist studying the integrals that appear throughout quantum field theory and string theory. These integrals are the building blocks of observables such as scattering amplitudes and cosmological correlators. By attacking them with geometry, chiefly twisted (co)homology and intersection theory, I reveal their hidden simplicity and build better algorithms for computing them.

As part of the Universe+ collaboration, I hold a joint position at the University of Amsterdam and the Institute for Advanced Study in Princeton, where I will move in fall 2027. Before that, I was a postdoc at Brown University. I received my PhD from McGill University in 2022, supervised by Simon Caron-Huot.

You can explore the graphical coaction for FRW cosmological correlators interactively at frwcoaction.ca.
