July 2003 - Aug 2016 Researcher 1989 to June, 2003 Associate Researcher 1987-1989 Assistant Researcher January-March 1987 Senior Research Specialist Aug 1971-1986 Specialist-Physical Sciences Research
Far Ultraviolet Spectroscopic Explorer (FUSE)(1998-2008)
FUSE, a satellite launched in 1999, explored the universe in the far ultraviolet at high spectral resolution. I processed hundreds of FUSE spectra which have been presented in several publications.
Ground-based observatory data (1985-present)
From 1989 - 2004 the UW Pine Bluff Observatory spectropolarimeter (HPOL) provided key ground-based observations in support of WUPPE and other astronomical research. I process HPOL data, incorporating final instrumental calibrations, monitor the quality of all processed data, archive data, and provide polarimetric information for the HPOL target database website. I delivered all PBO HPOL medium mode data (from February 1989 -October 2004) to the Mikulski Archive for Space Telescopes (MAST). During this time I worked with many graduate and undergraduate students.
Wisconsin Ultraviolet Photo-Polarimeter Experiment(WUPPE)(1983-1998)
WUPPE was a pioneering effort to measure polarization and photometry in the ultraviolet spectrum. It flew on two Space Shuttle missions (in 1990 and 1995) as part of the Astro Observatory. I provided data reduction support from initial testing at the Kennedy Space Center through both Shuttle missions at the Marshall Space Flight Center. During this time I supervised two people. I led the effort for planning and providing the sequences of commands for observing each astronomical target; was responsible for processing, reducing and analyzing WUPPE Astro-1 and Astro-2 data; and assisted in the calibration of WUPPE. After the data were processed and verified, I worked with the national Mikulski Archive for Space Telescopes in providing the astronomical community with WUPPE data, including detailed documentation.
Wide-Field Imaging Survey Polarimeter (WISP)(1993-1999)
WISP was a sounding rocket payload built to obtain wide-field polarimetric images in the ultraviolet. I wrote some software and assisted in processing the data.
Hubble Space Telescope (HST) Goddard High Resolution Spectrograph(GHRS)(1991-1993)
GHRS made finely detailed spectroscopic observations of ultraviolet sources. I provided initial GHRS data processing using pre-existing software.
HST High Speed Photometer(HSP)(1983-1984)
I reduced and analyzed test data for HSP, one of the original five instruments on the Hubble Space Telescope.
International Ultraviolet Explorer (IUE)(1978-1991)
Launched in January 1978, IUE took ultraviolet spectra of thousands of objects. I obtained, processed, analyzed and archived many IUE spectra using computer programs I developed. I worked with several graduate students in their thesis work.
Orbiting Astronomical Observatory (OAO-2)(1971-1982)
The first astronomical observatory in space, OAO-2 obtained ultraviolet spectra and photometry of planets, comets, stars, globular clusters and galaxies for the first time. I ran pre-existing programs on the large OAO-2 dataset; reduced OAO-2 spectrometer and photometer data; wrote analysis software; and published spectral atlases. I worked with several graduate students.
