My research interests are the generation of high brilliant x-ray pulses from the free-electron laser (XFEL) and the interaction between ultra-short high-intensity XFEL pulses and materials (atoms, molecular, clusters). The answers to this fundamental question would open doors for x-ray diagnosis, x-ray spectroscopy, x-ray imaging, and improvement of XFEL performances.
