Summary of Research

My research focuses on nuclear physics and fundamental quantum electromagnetic interactions. Specifically, I am investigating the process in which two electrons collide and emit a photon: radiative Møller scattering. This is a process that should, in theory, be well-known, and it is used as a baseline for a variety of nuclear physics measurements involving electron beams incident on atomic targets. However, existing calculations have been insufficiently precise for a number of modern experiments. In particular, they have neglected the effects of the electron mass.

My work has in part consisted of updating the theoretical calculations and programs we use to predict experimental results. I also work on the design and execution of a new experiment to precisely measure this process for the first time. The experiment is currently being commissioned at the MIT High Voltage Research Laboratory.
