Ultrafast Dynamics

This is a thematic subset of my publications focusing on ultrafast molecular dynamics induced by light. These studies were performed in collaboration with experiments conducted by the groups of Prof. Stephen Leone, Prof. Daniel Neumark, Dr. Oliver Gessner, and Prof. Graham Fleming.
