## Research Interests

Using a variety of theoretical and computational techniques, we study various aspects of the dynamics of atomic inner-shell phenomena. In particular, we are interested in radiative phenomena and those involving the rearrangement of atomic electrons as a consequence of nuclear decay or a collision process. The focus of this research is the role played by correlations and the influence of relativistic and QED effects.
