Jim is the Director of ASTeC. He has actively worked on numerous types of particle accelerator including synchrotrons, storage rings, linacs, energy recovery linacs, and fixed field alternating gradient accelerators. The prime focus of his career has been light sources of various types but he has also made contributions to particle physics colliders, neutrino factories, and industrial accelerators. He also has considerable breadth of expertise in key accelerator systems such as magnets, undulators, diagnostics, electron and positron sources, FELs, and beam dynamics. He has given more than forty invited talks and lectures at conferences, workshops, and schools on a wide variety of topics and has written two text books.
