Garth serves as the Lead Beamline Scientist for the Coherent Diffractive Imaging (CDI) beamline at 9-ID of the NSLS-II. CDI applies a type of lensless, or computational, x-ray microscopy to samples spanning a wide application space; however, its emphasis currently lies in the evaluation of (poly)crystalline materials. The techniques used by CDI produce nanoscale-resolution, three-dimensional representations of electron density and are sensitive to lattice deformation at the picometer scale.

Expertise

Garth has broad experience in the development and application of x-ray characterization techniques to scientific questions in fields ranging from the biosciences to hard condensed matter physics. His current focus is the development and implementation of imaging methods that use the optical properties of an x-ray beam, understanding of the interaction of those fields with matter, mathematical methods—especially in relation to inverse problems—and computational techniques to advance the information obtained via x-ray microscopy.

Education

B.S., Physics and Pure Mathematics, Univ. of Akron, USA.

M.S./Ph.D., Experimental Physics, Univ of Illinois at Urbana-Champaign, USA.
