Biography

Stephen Bradforth earned his PhD at the University of California, Berkeley in 1992 and carried out postdoctoral research at the University of Chicago.  Hestarted his independent career at USC in 1996 at the Department of Chemistry.  As a physical chemist, his lab designs experiments to gain a deeper understanding of how the inter-connected motions of molecules impact chemical reactions in complex but frequently encountered environments such as the aqueous milieu of cells or in functional molecular materials. His research applies ultrafast laser techniques to address contemporary scientific challenges such as UV damage to DNA, photochemistry, mechanisms for solar energy harvesting and condensed phase ionization and is funded by NSF, DOE and ONR.  His honors include a Packard Fellowship in Science and Engineering and a Cottrell Scholarship and STAR award from the Research Corporation for Scientific Advancement. He is Fellow of the American Physical Society, the Royal Society of Chemistry and the American Association for the Advancement of Science.

At USC, he has led the physical and theoretical chemistry section, and then served as vice chair (2013-4) and then department chair (2014-6).  As divisional dean, first for the Natural Sciences and Mathematics (2017-2020) and then for the Physical Sciences and Mathematics (2020-1), Bradforth coordinated strategic planning, faculty appointments and research advancement within the USC Dornsife Division of Natural Sciences and Mathematics. He is currently Senior Advisor to the Dean in the Dornsife College responsible for Research Startegy and Development.

  • Summary Statement of Research Interests

    The research in the Bradforth group centers on understanding the ultrafast dynamics of chemical reactions in solution and in complex condensed phase systems such as nucleic Acids and polymers. The common strand in our experiments is to explore the coupling of reactive transformations to the dynamics of the environment. The time scales for reactive processes such as bond breaking or non-adiabatic transformations are on the order of 100 fs; likewise the timescales of solvent or other surrounding motions are 10 fs – 1 ps. In a condensed environment, this allows only a short time window to explore the system evolution and catch the newly-formed products before complete relaxation. Femtosecond spectroscopy is therefore the appropriate experimental technique to elucidate the dynamics. Systems of interest extend from ionic solutes in water, radiation chemistry of pure water and aqueous systems, solar energy harvesting and conversion, and the mechanisms of deactivation and damage of DNA after UV exposure .
