Particle accelerators have been one of the most productive tools of physics in the past century. Much of what we know about the basic workings of matter at the smallest scales has been discovered and explored by means of high energy, dense particle beams produced in particle accelerators. I initially appreciated that there were important problems to solve in particle beam dynamics that I could make progress on immediately. There is also a breadth to the physics problems in accelerator physics that covers many of the tools and techniques used throughout all of physics. I have worked on a wide range of questions related to particle accelerators and beams including intrabeam scattering, linear coupling perturbation theory, non-linear dynamics, collective instabilities, synchrotron radiation emission and propagation including reduced models of partial coherence and application and theory of Wigner functions. I have also been involved in many particle beam and x-ray optics software projects, including Tracy, Accelerator Toolbox, Elegant, Synchrotron Radiation Workshop and Shadow. While at RadiaSoft, I contributed to the Sirepo web-based interface to a number of these codes.

I enjoy trying to find common ground between different projects, motivating people to solve the hard problems and improve usability and documentation in the software.
