Mary Katharine Gaillard is an American theoretical particle physicist. She is a professor of the Graduate School at the University of California, Berkeley and Visiting Scientist at the Lawrence Berkeley National Laboratory. She was Berkeley's first tenured female physicist. Her research accomplishments include pioneering work with Benjamin W. Lee on the evaluation of strong interaction corrections to weak transitions, including the successful prediction of the charmed quark mass; work with John Ellis and others on the analysis of final states in electron-positron collisions, including the prediction of three-jet events, and studies of unified gauge theories, including the prediction of the bottom quark mass; studies with Michael Chanowitz of signatures at proton-proton colliders which showed, on very general grounds, that new physics must show up at sufficiently high energies. Her work in recent years has focused on effective supergravity theories based on superstrings, and their implications for phenomena that may be detected both in accelerator experiments and cosmological observations.
