Long Citation
Lisa Jeffrey made fundamental contributions to symplectic geometry, moduli spaces and mathematical physics. Her groundbreaking work with Frances Kirwan led to their celebrated proof of the Witten formulas for stable vector bundles, a landmark achievement in the theory of moduli spaces; their techniques are now standard tools in symplectic geometry and other areas of mathematics and physics. The interdisciplinary nature of Jeffrey's work has an enormous value to both mathematics and theoretical physics, and especially to quantum field theory and string theory. Jeffrey's research accomplishments have been honoured by the André-Aisenstadt Prize, a Sloan Fellowship, a Premier's Research Excellence Award, the McLean Award, the Krieger-Nelson Prize, the Coxeter-James Prize, and a Steacie Fellowship.
