X-ray Multi-Mirror Mission, and an observer at the radio facilities Very Large Array, Dominion Radio Astrophysical Observatory, Institut de Radio Astronomie Millimétrique, and the optical facility Michigan-Dartmouth-MIT Observatory. Dr. Bregman serves on the NASA Astrophysics Working Group, High Energy Archive Working Group, and Infrared Processing and Analysis Center Users Committee. He is a member of the American Astronomical Society and the International Astronomical Union.

Michael J.Folk is a technical program manager at the National Center for Supercomputing Applications (NCSA), University of Illinois. His professional interests are primarily in the area of scientific data management. He has led the HDF (Hierarchical Data Format) Project at NCSA since 1988. Through his work with HDF, Dr. Folk is involved with data management issues in NASA and the earth science community, particularly the Earth Observing System Data and Information System. He has also led the effort to provide a standard format to address data management needs of the U.S. Department of Energy’s ASCI project, which involves data input/output, storage, and sharing among terascale computing platforms. Before coming to NCSA, Dr. Folk taught computer science at the university level for 18 years. Among Dr. Folk’s publications is the book File Structures: A Conceptual Toolkit.

Richard G.Kron is a professor in the Department of Astronomy and Astrophysics at the University of Chicago. He is also a scientist at the Experimental Astrophysics Group, Fermi National Accelerator Laboratory (Fermilab). His research interests include studies of galaxies with the Hubble Space Telescope and ground-based telescopes. One of Dr. Kron’s responsibilities within the Experimental Astrophysics Group is monitoring the efficiency of data acquisition for the Sloan Digital Sky Survey. The Fermilab group is responsible for processing the imaging and spectroscopic data of the Sloan Digital Sky Survey. He has served in the position of scientific spokesperson for the Sloan Digital Sky Survey since July 2001. Dr. Kron’s prior National Research Council service includes membership on the Steering Committee for the Task Group on Space Astronomy and Astrophysics, Panel on Cosmology, and the Space Studies Board.

James F.W.Purdom is a senior research scientist at the Cooperative Institute; for Research in the Atmosphere (CIRA) at Colorado State University. Before joining CIRA in 2001, he spent four years as director of the Office of Research and Applications in the National Oceanic and Atmospheric Administration’s National Environmental Satellite, Data, and Information Service. Dr. Purdom’s research focuses on remote sensing of the earth and its environment from space, as well as the development and evolution of atmospheric convection, with an emphasis on the study of mesoscale processes using satellite data. He received the U.S. Department of Commerce Silver Medal in 1994, the National Weather Association Special Award in 1996, and the American Meteorological Society Special Award in 1997. He currently chairs the World Meteorological Organization’s Commission on Basic Systems Open Program Area Group on Global Observing Systems.
