About Us


Our research group investigates how materials evolve on atomic- and nano-length scales as they change from one form to another. In particular, we use real-time x-ray techniques to examine structural evolution during phase transitions, thin film growth, and surface processes.

Many of our experiments utilize the high brightness of synchrotron x-ray sources, such as the National Synchrotron Light Source (NSLS) at Brookhaven National Laboratory on Long Island, the Advanced Photon Source (APS) at Argonne National Laboratory outside of Chicago, and the Linac Coherent Light Source (LCLS) at the SLAC National Accelerator Laboratory near Stanford University.

We are actively involved in new beamlines planned for the NSLS-II project now under construction at Brookhaven; Prof. Ludwig is Spokesperson for the Integrated In-Situ and Resonant (ISR) Beamline Advisory Team (BAT) and is a member of the Coherent Hard-X-ray (CHX) BAT. Where possible, our research makes contact with fundamental theory and simulation.
