Dwayne Miller, (born 18 April 1956) is a Canadian chemist and a professor at the University of Toronto.
His focus is in physical chemistry and biophysics.
He is most widely known for his work in ultrafast laser science, time-resolved spectroscopy, and the development of new femtosecond electron sources.
His research has enabled real-time observation of atomic motions in materials during chemical processes and has shed light on the structure-function correlation that underlies biology.
