Lisa Jeffrey
Lisa Claire Jeffrey is a Canadian mathematician, a professor of mathematics at the University of Toronto. In her research, she uses symplectic geometry to provide rigorous proofs of results in quantum field theory. Jeffrey graduated from Princeton University in 1986. She was awarded the Marshall Scholarship and obtained her doctorate from the University of Oxford in 1991, under the supervision of Sir Michael Atiyah. After postdoctoral studies, she became an assistant professor at Princeton in 1992, moved to McGill University in 1995, and moved to her present position at Toronto in 1997. Jeffrey was the 2001 winner of  the Krieger–Nelson Prize and the 2002 winner of the Coxeter–James Prize. In 2007 she became a fellow of the Royal Society of Canada, and in 2012 she became a fellow of the American Mathematical Society. She was chosen to give the Association for Women in Mathematics-American Mathematical Society 2017 Noether Lecture at the Joint Mathematics Meetings.
