Biographical sketches of authors

William T. C. Kramer National Energy Research Scientific Computing (NERSC) Division, Lawrence Berkeley National Laboratory, One Cyclotron Road, Berkeley, California 94720 (WTKramer@lbl.gov). As NERSC Center General Manager and Division Deputy, Mr. Kramer is responsible for NERSC computational facilities and support. Prior to his Berkeley Laboratory appointment, Mr. Kramer was a member of the NASA Ames Research Center, where he was Chief of Advanced Air Transportation Technologies and was responsible for creating and implementing a research and development program for designing revolutionary new air traffic management systems. From 1988 to 1994, he was Branch Chief of NASA's Numerical Aerodynamic Simulation (NAS) Computational Services Branch, responsible for all aspects of operations and customer service for NASA's principal supercomputer center. He holds B.S. and M.S. degrees in computer science from Purdue University, an M.E. degree in electrical engineering from the University of Delaware, and, following his commitment to continuous education, he is a Ph.D. candidate in computer science at the University of California at Berkeley.

Arie Shoshani Computational Research Division, Lawrence Berkeley National Laboratory, One Cyclotron Road, Berkeley, California 94720 (AShoshani@lbl.gov). Dr. Shoshani has been Group Leader of the Scientific Data Management Research and Development Group at the Lawrence Berkeley National Laboratory since 1978. The group's research activities focus on the development of algorithms and software for the organization, access, and manipulation of scientific databases. Dr. Shoshani's own technical work is mainly in the characterization of the unique requirements of scientific databases, query languages, modeling of statistical data, temporal data, sequence data, multidimensional data, data compression, and mapping techniques from extended entity-relationship schemas into relational schemas. He has been involved with several scientific projects, including the Human Genome Project, an epidemiological database for exposure to low-level radiation, the optimization of climate modeling data on tertiary storage, and the indexing and organization of high-energy physics data on tertiary storage. He received M.A. and Ph.D. degrees in computer sciences from Princeton University and a B.S. degree in control engineering from the Technion– Israel Institute of Technology.

Deborah A. Agarwal Computational Research Division, Lawrence Berkeley National Laboratory, One Cyclotron Road, Berkeley, California 94720 (DAAgarwal@lbl.gov). Dr. Agarwal is Group Leader of the Collaboration Technologies Group and Department Head in the Distributed Systems Department at the Lawrence Berkeley National Laboratory. She has been a project leader responsible for the design and development of software to allow remote experimentation and collaboration between sites connected by a wide-area network. As an expert on reliable multicasting, she served as an advisor to the Preparatory Committee of the Comprehensive Test Ban Treaty Organization, and in recognition of her contribution was voted one of the Top 25 Women on the Web. Dr. Agarwal received a Ph.D. degree in electrical and computer engineering from the University of California at Santa Barbara.

Brent R. Draney National Energy Research Scientific Computing (NERSC) Division, Lawrence Berkeley National Laboratory, One Cyclotron Road, Berkeley, California 94720 (BRDraney@lbl.gov). Mr. Draney is a member of the NERSC Networking and Computer Security Group. He received a B.S. degree from the University of Utah and has carried out graduate course work in statistics.

Guojun Jin Computational Research Division, Lawrence Berkeley National Laboratory, One Cyclotron Road, Berkeley, California 94720 (G_Jin@lbl.gov). Mr. Jin received a B.S. degree in computer technique from Beijing Industrial University and an M.S. degree in computer science from San Francisco State University. His research and development interests include gigabit network-based distributed applications for scientific imaging and the use of video for dynamic object analysis and laboratory control; acquisition, storage, processing, analysis, editing, and display of a variety of scientific image data (MRI, video, etc.); algorithms on concurrent programming (thread, SIMD, and MIMD) for speeding up image processing, analysis, and visualization of three-dimensional images; and the development of high-speed network interface and system software.

Gregory F. Butler National Energy Research Scientific Computing (NERSC) Division, Lawrence Berkeley National Laboratory, One Cyclotron Road, Berkeley, California 94720 (GFButler@lbl.gov). Mr. Butler holds a B.A. degree in astronomy from Northwestern University. He has more than twenty years of experience in high-performance scientific computing at federal installations, including system administration, software maintenance, and upgrades of high-performance production scientific computing systems. He also has more than ten years of experience in operating system development on multiple high-performance scientific computing platforms and operation systems.

John A. Hules Information Technologies and Services Division, Lawrence Berkeley National Laboratory, One Cyclotron Road, Berkeley, California 94720 (JAHules@lbl.gov). Mr. Hules received a B.A. degree in philosophy from Borromeo College of Ohio. He is currently a science writer and technical editor for the Computing Sciences organization at the Lawrence Berkeley National Laboratory. He previously worked in corporate and marketing communications for environmental and civil engineering firms.
