1994-1997:

The Johns Hopkins University Applied Physics Laboratory, Space Department, Science and Analysis Branch. Analyzed Midcourse Space Experiment (MSX) satellite far ultraviolet scanning spectrometer data. Calibrated the SSUSI ultraviolet imaging spectrometer for flight on a DMSP satellite. Analyzed data from the Atmospheric Explorer-E satellite for a NASA Supporting Research and Technology grant (Principal Investigator and Program Manager at JHU/APL).

1993-1994:

National Research Council Research Associate at the NASA Goddard Space Flight Center, Laboratory for Extraterrestrial Physics. Analyzed satellite (thermospheric neutral wind) data for evidence of the Sun-Earth Connection. Developed a technique to analyze satellite (electron spectrometer) data in a novel way in order to study thermospheric dynamics. Science Team member for the NASA Goddard Laboratory for Atmospheres Shuttle Ozone Limb Sounding Experiment. Recieved Service Award from NASA's Laboratory for Extraterrestrial Physics, Oct. 28,1994.

1993:

Postdoctoral Fellow, The Johns Hopkins University. Designed and built an improved high resolution coincident electron impact spectrometer for the laboratory measurement of electron impact ionization-excitation branching ratios.

1987-1992:

Ph.D. Candidate, The Johns Hopkins University. Developed a high resolution coincident electron impact spectrometer for the laboratory measurement of branching ratios (electron impact ionization-excitation of N2). Determined the electron impact ionization-excitation branching ratios of N2.

Patent:

Large geometric factor charged particle spectrometer. U.S. Patent number 6,703,612 issued 3/9/04.
