David became passionate about quantum field theory and general relativity while attending MIT for undergraduate studies. During his graduate studies at UCLA, he worked on efficient scattering amplitude methods for the Yang–Mills theory and its relation to solutions of gravity. His PhD thesis discussed how to compute gravitational radiation from Feynman diagrams. This further demonstrated that theoretical methods used for the LHC can be relevant for LIGO, two of the largest experimental endeavors. David is also interested in the application of exceptional mathematics to describe quantum gravity beyond the standard model physics.
