The rise of data-driven sciences and the recent surge of generative AI have contributed to an overwhelming flood of data, making it increasingly critical to amplify both experts' and casual users' capabilities to interact with data. In this talk, I will present our work on this challenge, spanning two stages of human-data interaction: data preparation and data analysis. For data preparation, in th...

Diffractive x-ray optics have interesting properties that make them highly attractive for use with x-rays and play a key role in the shaping, direction, and detection for a variety of experiments. In contrast to other kinds of x-ray optics such as mirrors and lenses, diffractive optics allow for precise control of the optical wave front and the realization of complex optical functionalities. The k...

Understanding how materials evolve under non-equilibrium conditions requires experimental tools capable of capturing both local structural changes and their ultrafast dynamics. Ultrafast X-ray pair distribution function (uf-PDF) analysis—based on total scattering measurements enabled by femtosecond X-ray free-electron lasers (XFELs)—now allows direct access to transient local structures beyond the...
