The research focuses on ultra-intense electron and x-ray sources for directly observing atomic motions during primary events, and ultrafast imaging over the relevant length and time scales to come to new levels of understanding of the interplay between structure and dynamics. Specific areas include theoretical and experimental aspects of condensed matter and atomically resolved dynamics, fundamental light-matter interaction, accelerator-based light sources, coherent imaging, coherent controlled molecular and solid state dynamics, molecule imaging, extreme timescale spectroscopy, ultrafast optics and x-ray science, relevance and applications in chemistry, biology and medicine.
