John W. Lyons, Chair, National Defense University, has directed two major federal science and engineering laboratories. He is a physical chemist with degrees from Harvard College and Washington University in St. Louis, Missouri. He began his career in research and development positions with the Monsanto Company for 18 years. In 1973 he joined the Commerce Department’s National Bureau of Standards (NBS) at Gaithersburg, Maryland. At NBS Dr. Lyons was the first director of the Center for Fire Research and then in 1978 the first director of the National Engineering Laboratory, a unit that came to include about half of the NBS programs. In 1990, Dr. Lyons was appointed by President George H.W. Bush to be the ninth director of NBS, by that time renamed the National Institute of Standards and Technology (NIST). In September 1993, he was appointed the first permanent director of the U.S. Army Research Laboratory (ARL). At ARL, Dr. Lyons managed a broad array of science and technology programs. Dr. Lyons has published four books and over 60 papers, and he holds a dozen patents. He was elected to the National Academy of Engineering in 1985. He is a fellow of the American Association for the Advancement of Science and of the Washington Academy of Sciences and a member of the American Chemical Society and of Sigma Xi.
David Arnett is professor of astrophysics at the Steward Observatory of the University of Arizona. He is a theoretical astrophysicist who first demonstrated how explosive nucleosynthesis in supernovae produces the elements from carbon through iron and nickel. He constructed quantitative theoretical models of evolving massive stars and showed that the ejecta produce a good fit to the abundance of heavy elements in the galaxy. His research interests include nuclear astrophysics, formation of neutron stars and black holes, high-performance computers, theoretical physics, hydrodynamics, thermonuclear burning, stellar evolution, computer graphics, and computer modeling. Dr. Arnett is a member of the National Academy of Sciences.
Alok N. Choudhary is chair of the Electrical and Computer Engineering Department at Northwestern University. He also holds an adjunct appointment with the Kellogg School of Management in marketing and technology innovation. In 2000, he cofounded Accelchip, Inc., a developer of electronic design
