He was the first Taiwanese Nobel Prize laureate, who, along with the Hungarian Canadian John C. Polanyi and American Dudley R. Herschbach won the Nobel Prize in Chemistry in 1986 "for their contributions to the dynamics of chemical elementary processes." Lee's particular Physical chemistry work was related to the use of advanced chemical kinetics techniques to investigate and manipulate the behavior of chemical reactions for relative large molecules using crossed molecular beams . From January 15, 1994 to October 19, 2006, Lee served as the President of the

At the war's end he resumed formal schooling and received a B.S. from National Taiwan University (1959) and M.S. from Tsinghua University (1961). He then came to the U.S. and took his Ph.D. with Bruce Mahan at the University of California, Berkeley (1965). After the postdoctoral year with Herschbach he joined the University of Chicago faculty (1968). In 1974 he moved to the University of California, Berkeley, ... [as a] Graduate Professor.' He became an American citizen the same year. 'In the 1980s, Berkeley Lab chemist Yuan T. Lee attempted to understand what occurs during a chemical reaction at the atomic scale. Lee and colleagues sought to examine the forces operating between atoms and molecules during chemical reactions in order to find out exactly how, and at what rate, these reactions take place. To follow the motion of atoms and molecules as they collide and react to form new products and to observe the flow of energy between them, Lee used a technique called "crossed molecular beams." Two beams of selected molecules were accelerated at supersonic speeds, then sent on a collision course in a vacuum. When the beams hit, the angles at which the resulting products are scattered and the amount of energy released during the collision are recorded. By controlling the content and velocity of the beams, and the angle at which they approach one another, Lee and his research team were able, in essence, to "view" chemical reactions as they occur.
