Bradley J. SiwickView profile
Associate Professor
Bradley J. Siwick is an Associate Professor in the Department of Chemistry at McGill University, holding the Canada Research Chair in Ultrafast Science (Tier II). He specializes in developing ultrafast electron-based techniques to study atomic and molecular dynamics in materials and chemical systems. His work bridges chemical physics, materials science, and condensed matter physics, focusing on structural dynamics, phase transitions, and nonequilibrium states. Education: B.A.Sc. (Engineering Physics, University of Toronto, 1997), M.Sc. (Physics, 1998), Ph.D. (Physics, 2004). Postdoctoral training at FOM-AMOLF Amsterdam (2004–2006). Awards: NSERC Doctoral Prize (2005). Research interests include ultrafast electron diffraction/scattering, electron-phonon coupling, and imaging transient structural changes. Techniques developed in his lab combine electron microscopy with ultrafast laser spectroscopy to observe atomic motions on femtosecond timescales. Key areas of study are phase transitions in materials (e.g., VO₂, cuprates), nanocomposites, and extreme states of matter using facilities like the Advanced Laser Light Source (ALLS). Recent articles highlight advances in momentum-resolved phonon dynamics, polaron formation, and ultrafast imaging of 2D materials. His lab, based in Otto Maass and Rutherford buildings, collaborates on frontier projects in nonequilibrium materials science. Advising: Leads the Siwick Research Group, focusing on graduate students in chemical physics and materials science. Grants: Supported by NSERC and Canada Research Chairs funding. Labs and facilities: Otto Maass 25 laboratory and ALLS (Varennes, Quebec) for high-power laser experiments.
