Phillips is an American physicist best known for his pioneering work on laser cooling and the trapping of a toms. For the development of techniques that use laser light to slow atoms to extremely low temperatures - enabling breakthroughs in precision measu rement and atomic physics - he was awarded the 1997 Nobel Prize in Physics \, jointly with Steven Chu and Claude Cohen-Tannoudji. Phillips spent much of his career at the National Institute of Standards and Technology and a lso served as a professor at the University of Maryland\, where he is high ly regarded for both his research and his commitment to science education.
