• Professor of Physics and Materials Science and Engineering, Carnegie Mellon University

• Carnegie Mellon (1981 - present)
• Visiting Scientist, IBM Research, Yorktown Heights, NY (1979-1981)
• PhD in Physics, Clark University, Worcester, MA
  

Activities

• Active APS Sector 1 user under GUP and PUP programs
• Proposal Review Panel for Scattering, Applied Materials at APS (2009 - present)
• Sector 1 beamline advisory group (2009 - present)

Experience and Interests

• Development and application of High Energy X-ray Diffraction Microscopy at APS Sector 1; this is a technique for mapping microstructures inside bulk polycrystals that allows direct observation of responses to thermal and mechanical treatments.
• Have done measurements at APS, ESRF, CHESS, NSLS, and SSRL studying two dimensional phases, lipid membrane structure, and polycrystalline materials. Laboratory x-ray reflectivity measurements have probed complex thin fluid films on solid surfaces.
• Strong interest in helping the APS take advantage of its unique position among US synchrotron sources by i) advocating for appropriate resource allocation directions, ii) making user and staff needs known to management and iii) assisting communications between management and users and staff.
