Research Interests

Jum's general research interests lie in the areas of atomic physics and computational physics. To be more specific, Jim is interested in the calculation of atomic structure and electron(positron)-atom collisions. For the last five years most of Jim's research has been concerned with studying the interactions between positrons and atoms.
