Research Interests

My primary research interests are rotational spectroscopy of small fundamental molecules in the millimeter and submillimeter microwave region, variable temperature pressure broadening studies of microwave spectral lines, and millimeter and submillimeter microwave generation and detection. In addition to providing basic information on molecules in the ground and excited vibrational states, such molecular investigations can provide laboratory support for radio astronomy studies of molecules in interstellar clouds and for upper atmospheric research programs related to the molecules participating in the ozone cycle.

My current research collaborations include work on laboratory studies of molecules involved in the ozone cycle in the upper atmosphere with colleagues at the University of South Alabama, at The Ohio State University, and at Justus Liebig Universität in Giessen, Germany. Overall publications include more than 60 articles in refereed journals and an equivalent number of presentations at professional society meetings.
