    Doctoral, master’s, and bachelor’s degrees in experimential physics. Five years research experience in experimental plasma physics. 23 years experience in the calibration, characterization and development of remote sensing instruments for atmospheric applications in the retrieval of ozone and other trace gases important to understanding tropospheric and stratospheric chemistry. Broad experience in experimental physics, measurement techniques, optical systems, spectroscopic measurements, computer controlled data acquisition, numerical techniques in data analysis and modeling, and computer programming.
