Scope of Research:

• Group leader of the ORNL Materials Science & Technology Division, Diffraction & Thermophysical Properties Group. The group is responsible for the activities in the Residual Stress, Diffraction, and Thermophysical Properties User Centers within the High Temperature Materials Laboratory User Program. These activities all contribute to laboratory-industry-university collaborative research aimed at improving advanced materials processing and properties with particular emphasis on high temperature structural ceramics and alloys.
• Principal investigator on two multidisciplinary ORNL development projects "Development and Demonstration of Residual Stress Mapping by Neutron and X-ray Diffraction Methods" and "Three Novel Neutron Based NDE Techniques for Materials Characterization". The former has led to the on-going program on nondestructive mapping of strains throughout the volume of research and industrial specimens.

Broad Fields of Endeavor:

• X-ray and neutron diffraction and thermophysical property measurement techniques to enhance the understanding and development of advanced materials processing, stability, properties, and behavior.
