Yusong Liu
Staff Scientist, SLAC National Accelerator Laboratory
BioI am a Staff Scientist in the LCLS Chemical Sciences Department at SLAC National Accelerator Laboratory. My research focuses on the excited-state dynamics of small organic molecules, with a particular emphasis on employing novel experimental techniques to probe these processes in real time and space.
Because these dynamics typically occur on attosecond to picosecond timescales, the strongly coupled electronic and nuclear motions drive ultrafast energy redistribution and structural transformations, processes that underpin fundamental phenomena across physics, chemistry, and biology.
Building on my extensive background in ultrafast laser science and time-resolved spectroscopy, my current work involves developing multi-modal experiments that integrate spectroscopy and diffraction. My toolkit includes time-resolved valence and soft X-ray core-ionization spectroscopy, as well as ultrafast electron and hard X-ray diffraction. These studies are conducted primarily at the LCLS X-ray FEL, the MeV-UED facility at SLAC, and our tabletop laser laboratories at the Stanford PULSE Institute.
