Neutron and X-Ray Scattering

We use a variety of neutron and x-ray techniques to investigate the structure and dynamics of energy and quantum materials with properties that emerge from the presence of local defects and complex short-range correlations.

The objective of our research is to obtain an understanding of the critical roles of local disorder and short-range correlations in driving materials properties of importance for future energy applications. To progress towards this goal, we develop and utilize advanced methods based on neutron and X-ray scattering techniques to characterize and so determine the origin, nature, and consequences of the different long- and short-range ordered states found in crystalline materials with a variety of properties of interest. This knowledge is crucial for enabling the design of novel materials with desired functionality.
