Short presentation
I am a researcher and group leader in the Chemical and Bio-Molecular Physics program. My group uses short light pulses spanning the THz, optical and X-ray range to study how orbital-level charge dynamics drive homogeneous catalytic reactions in the fields of light-harvesting and bond activation.
