ence of laser cooling and manipulation of ions, with applications in precise measurements and standards, quantum computing, and fundamental tests of quantum mechanics; his major impact on the international scientific community through the training of scientists; and his outstanding publications.

David Wineland joined the U.S. Department of Commerce's National Institutes of Standards and Technology (NIST), when it was the Bureau of National Standards. As leader of the Ion-Storage Group in the Time and Frequency Division at Bolder, CO, his research concentrates on laser cooling and spectroscopy of trapped atomic ions with applications to atomic clocks, quantum-limited metrology, and quantum start control. Wineland's work led to the development of laser-cooled atomic clocks, the current state of the art in time and frequency standards.

Wineland is internationally recognized for developing the techniques of using lasers to cool ions (electrically charged atoms or molecules) to near absolute zero, the coldest possible temperature. He achieved the first demonstration of laser cooling and has built on that breakthrough with thirty years of experiments that represent the first or best in the world-often both-in using trapped laser-cooled ions to test theories in quantum physics and demonstrate crucial applications such as new forms of computation.

Wineland received his bachelor's degree from the University of California Berkeley and master's and doctoral degrees in physics from Harvard University, where his advisor was Norman Ramsey, a 1989 Nobel Laureate in physics. Before joining NIST, Wineland worked as a postdoctoral research associate at the University of Washington with Hans Dehmelt, who shared the 1989 Nobel Physics prize with Ramsey.
