, from where he received his Ph.D. in physics in 1967 after completing a doctoral dissertation, titled "de Haas-van Alphen effect and electronic band structure of nickel", under the supervision of Royal Stark. He remarked that due to the influence of prominent Chinese theoretical physicists and Nobel laureates C. N. Yang and T. D. Lee, both of whom studied at the University of Chicago, he had always knew that he wanted to pursue graduate studies in physics at the institution. While a graduate student at the University of Chicago, Tsui met Linda Varland, who was an undergraduate student there at the time, and the two married after the latter's graduation. Tsui is a naturalized U.S. citizen. Tsui and Varland have two daughters, Aileen and Judith.

to perform research in solid state physics in 1968. At Bell Laboratories, instead of studying mainstream topics of interest in semiconductor physics such as optics and high energy band-structures or their applications in devices, Tsui devoted his attention to a new field called the physics of two-dimensional electrons. Tsui and Störmer made the groundbreaking discovery of the

in 1982, while Laughlin provided a theoretical interpretation for the discovery the following year. This discovery will eventually be the reason of their winning of the 1998 Nobel Prize in Physics. Shortly after the discovery, Tsui departed from Bell Laboratories and joined the faculty of the Department of Electrical Engineering and Computer Science at Princeton University with the support of two Nobel laureates in February of 1982. After 28 years at Princeton, Tsui transferred to emeritus status in 2010. He was also an adjunct senior research scientist in the physics department of
