This list updates the one published in the first issue of Legacy. It includes new members of the science and science support teams and all members of the programming staff.


Laura A. Whitlock received her Ph.D. in Physics from the University of Florida in 1989. She did most of her dissertation work with the Space Astronomy and Astrophysics Group at Los Alamos National Laboratory. There she was responsible for reorganizing the Vela 5B database into a more accessible, user-friendly structure. Her interests range from the time variability of X-ray binaries to the development of gamma-ray imaging systems.

Patricia Tyler received an AA with mathematics emphasis from Del Mar College in Corpus Christi, Texas in 1985, and a BS in Physics from Texas A&I University in 1989. She is currently a graduate student in the Physics Department at the University of Maryland, College Park. While at Texas A&I, Pat worked with professors on a NASA grant to study the dynamics of deployment of a tethered satellite. (The SEDS project will be flown on a Delta ELV in 1993.) At the University of Maryland, she worked for two years as a research assistant with the Astro-Metrology Group, processing and archiving images from various NASA missions including the Hubble Space Telescope. Pat joined the HEASARC in September of 1991 where she assists in the testing, maintenance, and documentation of the BROWSE software; ingests data sets into HEASARC databases; and performs various administrative tasks for the group.

Programming Staff

Orin Day received a BS in Physics and a BS in Mathematics from Duke University in 1991. From August 1989 until May 1991 he was an undergraduate research associate in the Duke Physics Department. This position in a research group studying "quantum chaos" involved simulation and experiment exploring modal distributions resultant from the injection of monochromatic light into optical fibers of irregular cross-section. From May 1991 until May 1992 he held a teaching assistantship at Duke where he studied convection in high aspect ratio systems containing dilute 3He-4He mixtures at low temperature and below the superfluid threshold. Mr. Day joined the HEASARC in May 1992 and is responsible for the development and enhancement of analysis software as well as maintenance and support of the XANADU software conglomeration.

Paul Jacobs received a Bachelor's degree in Physics from the University of Chicago and a Master of Science degree in Electrical Engineering from the University of Oklahoma. He also studied for the Ph.D. degree in Electrical and Computer Engineering at the University of Michigan. He has held positions in systems and software engineering at Arizona Public Service Company and at Westinghouse Electric Corporation. Mr. Jacobs joined the HEASARC project in January, 1991 where he works on the development of graphical user interfaces and on the HEASARC implementation of the Astrophysics Data System.

Bruce O'Neel received a BS in Electrical Engineering from University of Maryland, College Park in 1986. From October 1984 until December 1987 he worked part-time at GSFC for the Geodynamics group doing VMS and unix scientific and system programming. From July 1986 until March 1989 he worked at a small telephone equipment manufacturing company doing system management and systems programming on VMS systems. Next he worked for Electronic Data Systems working on different contracts doing VMS programming and unix system management. In January 1991 he joined the HEASARC where he performs VMS and unix program development and maintenance.

Andy Pollock got his BA in Physics at Oxford University before going to Leeds to do a Ph.D. studying ultra-high-energy cosmic rays. He's been getting less energetic ever since, travelling via Saclay near Paris working on COS-B, Birmingham working on Ariel VI (ever hear of it ?) and EXOSAT data and the EXOSAT Observatory in Darmstadt and Noordwijk before setting up to work for himself in Sheffield in the north of England. His responsibilities for the database software at the HEASARC take up most of his time now but occasionally there is still time for Wolf-Rayet and other hot stars and for using likelihood for the statistical treatment of photon-limited data.

Song Yom received his BS in Mechanical Engineering from the University of Virginia in 1987. After graduation, he joined the COBE project at GSFC as a programmer analyst responsible for development and maintenance of ground systems software information and configuration management systems. He briefly worked for the UARS project at GSFC in 1990 as a systems engineer where he wrote the Ground Systems Interface documentation of the Flight Operations Team manual. He rejoined the COBE project as a task leader for software engineering and systems software partitions. In May of 1992, Mr. Yom joined the HEASARC project as a BROWSE systems programmer.
