Jacob Lewis Bourjaily

Associate Professor

I am a theoretical physicist with a joint appointment at Penn State University an the Niels Bohr Institute in Copenhagen. I completed my PhD in 2011 at Princeton University under the supervision of my advisor and collaborator Nima Arkani-Hamed at the Institute for Advanced Study, after which I spent three years at Harvard University as a Junior Fellow in the Harvard Society of Fellows.

The primary focus of my research has been the development of a recursive reformulation of perturbative quantum field theory based exclusively on physical observables, and improving the mathematical and computational tools needed to determine and evaluate scattering amplitudes in quantum field theory more generally.

This programme of research has important applications for predicting real observables for experiments such as the Large Hadron Collider at CERN, and has many deep connections to active areas of mathematical research involving graph theory, motivic cohomology, and the geometry of certain stratifications of Grassmannian manifolds.

I have also worked on string theory and particle physics phenomenology, with a particular interest in the local, geometric structures which can lead to physically interesting phenomenological models in M-theory and F-theory.
