  • Ph.D., University of Illinois at Urbana- Champaign
  • Current research activity focuses on the use of nanoscale X-ray diffraction microscopy as a probe of local structural physics in materials. This is associated with multiple related areas: observation of nanoscale phase phenomena in active materials, observation of unique material behavior of nanoscale objects, and observation of emergent critical dynamics in engineered mesoscale material systems.

  • Dr.rer.nat., RWTH Aachen University
  • Research focuses on the combination of synchrotron radiation with scanning tunneling microscopy and scientific applications of high-resolution X-ray microscopy.
