David K. Johnson, leader of the Site Utilities Division at the Laboratory, was elected to the Electrical Engineering Technical Advisory Committee of the California Board of Registration for Professional Engineers and Land Surveyors. He is one of two electrical engineers selected to serve.
The board of registration is part of the Department of Consumer Affairs and regulates professional engineering and professional land surveying practice in the state. “One of my jobs is to investigate technical issues for the board and advise them on electrical engineering issues,” Johnson says. “One thing the committee has talked about is the electricity crisis in the state, and I imagine that there will be technical issues that might be related to that.”
Johnson received a B.S. in electrical engineering from Iowa State University and an M.B.A. in marketing from the University of Iowa. He is also the recipient of the Vice President’s National Performance Award (the Hammer Award) for saving money in government.

Each year, the American Welding Society honors individuals who have made valuable contributions to the field of welding research, to the advancement of the welding industry, and to the society as a whole. At the society’s 2001 awards luncheon held recently in Cleveland, Ohio, Laboratory employees John Elmer and Joe Wong received the William Spraragen Memorial Award for coauthoring, with two others, the best paper published in the Research Supplement of the Welding Journal, “Evolution of Titanium Arc Weldment Macro and Microstructures—Modeling and Real Time Mapping of Phases.”
Elmer is a group leader for Livermore’s Material Joining Group, which is responsible for electron and laser beam welding, vacuum brazing, and diffusion bonding. He also is a principal investigator for a DOE Office of Basic Energy Sciences research program to investigate phase transformation kinetics during synchrotron radiation x-ray diffraction measurements of arc welds. Elmer has a Ph.D. in metallurgy from the Massachusetts Institute of Technology. He was named an American Welding Society Fellow in 2000.
Wong has B.Sc. degrees in pure and applied chemistry and physical chemistry from the University of Tasmania, Australia, a Ph.D. in physical chemistry from Purdue University, and a D.Sc. from the University of Tasmania. He joined the Laboratory in 1986 and is currently a senior staff chemist. Since 1995, he has also been consulting professor at the Stanford Synchroton Radiation Laboratory. He has published over 175 journal articles, coauthored a textbook, and been granted seven U.S. patents.
