Staff Scientist at the Theoretical Physics Department of the Stanford Linear Accelerator Center, Stanford University, Stanford, U.S.A.
President of non-profit Contemporary Physics Education Project, which produces material on contemporary topics for high school and college use.
Permanent staff member of the Stanford Linear Accelerator Center since 1979, she has made significant contributions to particle physics theory, for which she has received numerous honors.
Some Important Contributions :
· First paper to discuss how the strong, weak, and electromagnetic coupling constants can merge to a single coupling constant in a grand unified theory, with Howard Georgi and Steven Weinberg.
· Suggested a possible near symmetry of the universe (now known as Peccei- Quinn symmetry) to explain how strong interactions can maintain the symmetry between particles and antiparticles (CP symmetry) when weak interactions do not, with Roberto Peccei.
· Showed how physics of quarks can be used to predict some properties of the physics of hadrons (which are particles made from quarks),with Enrico Poggio and Steven Weinberg. This is now known as quark-hadron duality.
· Phenomenological analyses of CP violation in B meson decays in the standard model with the Kobayashi-Maskawa mass matrix.
