The general areas of research interest are in atomic, molecular and optical physics. Major applications in these areas belong to space physics, environmental monitoring, medical physics, and astrophysics. Our hope is to extend fundamental knowledge about the interaction of simple atomic and molecular systems in a variety of situations. The techniques we have applied to study such systems have involved ultra-high resolution tunable CW infrared lasers, tunable pulsed organic dye lasers, computer simulation and modeling of dynamical systems using supercomputers, free jet expansion of gases and sub Doppler spectroscopy. Recent work has included studies on the opacity of hydrogenic systems in Teragauss fields - as found near pulsars, development of optical wave meters for airborne laser monitoring of atmospheric species, creation of computer simulation methods in classical mechanics, analysis of optical collision data, and measurement of optical cross sections for use in applications of laser radar. Most recent work is in computer modeling of various physical systems:
