My research interest is the calculation of atomic properties using variational methods, either non-relativistic with Breit-Pauli corrections or fully relativistic methods based on Dirac theory. Codes for large-scale, parallel calculations have been developed and applied to a large number of atomic systems. Of particular interest are all possible types of transition probabilities between levels of a spectrum. The results have been collected in a database for energy levels, lifetimes, and transition probabilities, http://atoms.vuse.vanderbilt.edu.
