Brydges received in 1976 his Ph.D. from the University of Michigan with thesis advisor Paul Federbush and thesis A Linear Lower Bound for Generalized Yukawa Model Field Theories.[1] Brydges was a professor at the University of Virginia and is now a professor emeritus (formerly holding a Canada Research Chair) at the University of British Columbia in Vancouver.
Brydges is concerned with mathematical quantum field theory and statistical mechanics. His research deals with functional integral techniques (including supersymmetry techniques), cluster development techniques, renormalization group methods on problems of static mechanics, and probabilistic problems. In 1985 he and Thomas C. Spencer introduced "lace expansion" for the analysis of the self-avoiding walk.[2]
