R.J. Dwayne Miller

Professor R.J. Dwayne Miller FRS


Elected: 2023


R. J. Dwayne Miller has published over 300 papers in the field of coherent multidimensional spectroscopy and the development of ultrabright electron sources to directly observe atomic motions during the defining moments of chemistry.  He has achieved the fundamental space-time limit to imaging chemistry, revealing the enormous reduction in dimensionality that occurs during barrier crossing in the act of chemical transformation. The emerging picture illustrates how chemistry scales in complexity, with increasing nuclear degrees of freedom,  up to biological systems.

His research has been recognized with Sloan, Guggenheim, Dreyfus, and Humboldt Fellowships, the Polanyi Award, the Rutherford Medal, the Canadian Institute of Canada Medal, the American Chemical Society E. Bright Wilson Award in Spectroscopy, and the EPS Award in Laser Science for 'Achieving the Fundamental Limit to Minimally Invasive Surgery with Complete Biodiagnostics..'.

R. J. Dwayne Miller is also a strong advocate for science promotion earning the Royal Society of Canada's McNeil Medal for founding Science Rendezvous, which has made science accessible to the general public, inclusive of remote northern communities, with over 215,000 attendees, involving >6000 volunteers annually.
