Research interests

I'm developing computer programs and efficient methods for solving the non-relativistic and relativistic wave equations for atomic systems. From the wave functions different properties such as energy structure, hyperfine structure, isotope shifts, transition rates, and splittings due to external magnetic fields can be determined. Atomic data are needed to understand and model astrophysical and fusion plasmas. Combined with high precision experimental energy structures, computed atomic data can be used to infer properties of the atomic nucleus.
