Alexander is interested in the analysis of spectra of neutral and ionized atoms and is active in the critical compilation of atomic spectral data for NIST's atomic spectroscopy databases. He is currently involved in evaluation of energy levels, wavelengths, and transition probabilities in the spectra of beryllium and neon and spectra of all stages of ionization of tungsten. Utilizing his knowledge of computer programming, he assists in support of the on-line databases on atomic spectra.
