A. S. in Dallas 9/3/97

Research interests are: quantum-mechanical perturbation theory, summation of divergent perturbation series, quasiclassical methods for resonant states. Specifically, Stark effect and 1/D-expansion (where D is the dimensionality of space) for various quantum-mechanical problems, such as screened Coulomb potentials, Stark and Zeeman effects, helium-like ions, and two-centre-Coulomb problem. Recently, worked on self-consistent-field version of the semiclassical perturbation theory for molecules, new schemes to sum perturbation series for resonances, estimating stability of atoms with a variable nuclear charge (finding "critical" charges).
