  • Ph.D., University of Gottingen, Germany
  • Research interests include high-resolution X-ray optics, hard X-ray microscopy, and its application to nanoscale science, materials science, biological and medical science and environmental science. Experimental expertise is in X-ray fluorescence microscopy, X-ray diffraction, and transmission X-ray microscopy

Martin Holt, Assistant Physicist
Bldg 440 - Room A139, Phone: 630.252.5180, Fax: 630.252.5739, E-mail: mvholt@aps.anl.gov

  • Ph.D., University of Illinois at Urbana- Champaign
  • Current research activity is in the use of nanoscale diffraction microscopy as a probe of local structural physics in materials. This is broadly associated with two related areas: observation of novel nanoscale phase phenomena in active materials and observation of unique material behavior of nanoscale objects. Also active in development and commissioning of novel hard X-ray focusing optics (multilayer Laue lens) and frontier imaging techniques (divergent beam coherent Bragg diffraction imaging of disorder in solids).

  • Ph.D., Tulane University
  • Developing a full-field and tomographic X-ray research program using the unique capabilities associated with the design of the Hard X-Rray Nanoprobe Beamline
  • Studying nanoscale systems using polarized X-rays and applied electric and magnetic fields
