Lee is a faculty senior scientist in Berkeley Lab’s Materials Sciences Division and co-principal investigator in the Theory of Materials and Quantum Materials programs. He is also a professor of physics at UC Berkeley. Lee’s research focuses on condensed matter physics and materials science. The goal of his research is to uncover new states of matter and understand their physical properties.

Since joining UC Berkeley and Berkeley Lab in 1994, Lee has been credited with uncovering new insights into long-standing problems in theoretical condensed matter physics, such as high- temperature superconductivity, phase transitions in the quantum Hall effect, anyon superconductivity and symmetry-protected topological states, among many others.
