Born in Sarnia, Ontario, Douglas Andrew Bonn graduated from Northern Collegiate Institute and Vocational School in 1979 . He was awarded his B.Sc. in physics in 1983 and his Ph.D. in 1989. He earned both degrees at McMaster University in Hamilton, Ontario, which has long had a strong reputation in the physical sciences. As a graduate student, Bonn was one of the first scientists to use optical techniques to help determine the fundamental nature of several kinds of superconductors. This work won him an invitation to address the 1989 Spring Meetings of the American Physical Society. From 1989 to 1991, he was working as NSERC Postdoctoral Fellow at University of British Columbia (UBC). The following years Bonn joined UBC as Research Associate, Assistant Professor and Associate Professor. Since 2000 he is Professor of physics at UBC.

His main area of research is the study of high temperature superconductors, particularly their electromagnetic properties at microwave frequencies. The screening and absorption of electromagnetic radiation at these low frequencies provide some of the key means of probing the pairing state of electrons in superconductors, and the excitations out of that superconducting groundstate.
