Research Interests

My research focuses around microscopic and microspectroscopic imaging. The analysis of materials using infrared and x-ray fluorescence microspectroscopies, electron microscopy, radiography, and especially micro x-ray computed tomography are widely practiced. Materials examined include high explosives, aerogels, carbon fiber composites, foams, both polymer and metallic, and items of cultural provenance. These materials are examined to look at defects, voids, and the distribution of their component materials. Materials are examined in both 2D as well as 3D using confocal micro x-ray fluorescence and micro x-ray tomography.

Research has focused on quantification and statistical distribution of features within the materials as well as the overlay of imaging techniques in 2D and 3D. Recent accomplishments include the characterization of incipient spall in shocked materials, examining in-situ tension and compression samples in 3D, the overlay of 3D images from multiple techniques, and examination of 3D image acquisition parameters and required number of voxels within embedded objects for the most rigorous statistics

At Los Alamos, I started as a postdoctoral research associate in the Chemistry Division in 2004 with George J. Havrilla, where my research focused on the integration of micro infrared and x-ray fluorescence spectroscopic imaging for enhanced chemical understanding as well as 3D visualization techniques for confocal micro x-ray fluorescence. I obtained my PhD from Miami University, Oxford, OH in the lab of Andre’ J. Sommer. There, my work focused on the integration of attenuated total internal reflection Fourier-transform infrared microspectroscopy as a detection technique for high performance liquid chromatography and capillary electrophoresis. During this time, I was awarded a Coblentz Society student award. Prior to graduate school I taught for two years at Ohio public high schools. I obtained a Bachelor of Education with certificates to teach high school Chemistry, Physics and General Sciences from University of Toledo, Toledo, OH in 1997.
