Chemical reactions are traditionally understood by tracking how atoms move, how bonds stretch, break, and form. Yet beneath every structural transformation lies a far faster and more fundamental process: the motion of electrons. Our research seeks to directly observe and understand electron dynamics in real time, revealing how electronic motion initiates, guides, and sometimes dictates chemical reactivity. By developing and applying ultrafast spectroscopic techniques across isolated molecules and condensed environments, we aim to move beyond structural snapshots and toward an electron-centered framework of chemical dynamics, one that captures the true driving force of chemical change.
Our goal: Electron moves insanely fast. We try to catch them in the act!
Attosecond to picosecond time-resolved spectroscopy:
Elucidating how electrons move in molecules and materials, and how their motion drives structural changes.
Electron dynamics in diverse environments:
Understanding how environment influences electron dynamics and how electrons reveal quasi-paricle quantum characteristics in materials.
