Citizenship:
Field of Research: Theoretical Atomic Physics
Current Research:
I have been a professor of physics at the Louisiana School for Math, Science, and the Arts (LSMSA) since Fall 2000. My research field is computational atomic physics. I was a post doctoral student at Auburn University calculating electron-impact excitation and ionization cross-sections of positive ions on a DOE grant for fusion research. I also do semi-classical and quantum calculations for highly excited electronic states of atoms in electric and magnetic fields. Recent work has focused on atoms in electric fields and extensions of closed-orbit theory to include scattering in complex atoms. I am mainly a teacher at LSMSA, but also have supervised LSMSA students researching microseisms at LIGO and studying variable stars.
