However, again disrupted by further Japanese invasion, Lee continued at the National Southwestern Associated University

, where he remains today. His first work at Columbia was on a solvable model of quantum field theory better known as the Lee Model. Soon, his focus turned to particle physics and the developing puzzle of K meson decays. Lee realized in early 1956 that the key to the puzzle was parity non-conservation. At Lee's suggestion, the first experimental test was on hyperion decay by the Steinberger group. At that time, the experimental result gave only an indication of a 2 standard deviation effect of possible parity violation. Encouraged by this feasibility study, Lee made a systematic study of possible P,T,C and CP violations in weak interactions with collaborators, including C.N. Yang. After the definitive experimental confirmation by C.S. Wu and her collaborators of parity non-conservation, Lee and Yang were awarded the 1957 Nobel Prize for Physics.

In the early 1960s, Lee and collaborators initiated the important field of high energy neutrino physics. In 1964, Lee, with M. Nauenberg, analyzed the divergences connected with particles of zero rest mass, and described a general method known as the KLN theorem for dealing with these divergences, which still plays an important role in contemporary work in QCD, with its massless, self-interacting gluons. In 1974–75, Lee published several papers on "A New Form of Matter in High Density", which led to the modern field of RHIC physics, now dominating the entire high energy nuclear physics field.

Besides particle physics, Lee has been active in statistical mechanics, astrophysics, hydrodynamics, many body system, solid state, lattice QCD. In 1983, Lee wrote a paper entitled, "Can Time Be a Discrete Dynamical Variable?"; which led to a series of publications by Lee and collaborators on the formulation of fundamental physics in terms of difference equations, but with exact invariance under continuous groups of translational and rotational transformations. Beginning in 1975, Lee and collaborators established the field of non-topological solitons, which led to his work on soliton stars and black holes throughout the 1980s and 1990s.

Since 1997, Lee directed the RIKEN-BNL Research Center, which together with his Columbia group, completed in 1998 a 1 teraflops supercomputer QCDSP for lattice QCD. At present, a 10 teraflops QCDOC machine is under construction to be completed in 2004. Most recently, Lee and R. Friedberg have developed a new method to solve the Schroedinger Equation, leading to convergent iterative solutions for the long-standing quantum degenerate double-wall potential and other instanton problems.

In 1998, Lee established the Chun-Tsung Endowment (秦惠莙—李政道中国大学生见习基金) in memory of his wife, Hui-Chun Chin, who died 3 years earlier. The Chun-Tsung scholarships, supervised by the United Board for Christian Higher Education in Asia (New York), are awarded to undergraduates, usually in their 2nd or 3rd year, at five universities, which are Fudan University, Lanzhou university, Suzhou University, Peking University and Taiwan National Tsing Hua University. Students selected for such scholarships are named "Chun-Tsung Scholars" (莙政学者).
