Structural Science (SRS)

Primary Contact: Uta Ruett
Research Disciplines: Materials Science, GeoScience, Physics, Chemistry, Environmental Science

The scientific programs of the SRS group focus on the study of the structure of materials, both on a short-range scale using PDF methods and x-ray absorption spectroscopy, and also on a longer‑ length scale using high-resolution powder diffraction and single-crystal diffuse scattering. In situ, operando or time-resolved (i.e., pump-probe) studies are major themes of the group.
