- Cornell High Energy Synchrotron Source (CHESS) User’s Executive Committee
- APS user at beamline 1-ID-C
- Chair, APS Sector 1 Beamline Advisory Group
- Member, APS Technical Advisory Committee (TAC), Extreme Conditions. The 6 TACs will provide input for the APS upgrade proposal.
- Mechanics of engineering materials – understanding behaviors and development of constitutive models for mechanical design including plasticity, fatigue and fracture.
- In situ mechanical loading / high energy x-ray diffraction experiments for quantification of lattice strains and stresses on the size scale of the polycrystalline aggregate as well on the scale of the individual crystal and below.
- Diffraction experiments on semiconductor materials for understanding high temperature mechanical behavior associated with materials processing.
- I became an x-ray user rather “late in life” but now high energy x-rays are a central theme in my research. I therefore tend to have an affinity for novice users. I am a co-PI on a Partner User Project at beamline 1-ID-C specifically focused on lowering the barrier for new users of high energy x-ray diffraction methods. The new generation of engineers and materials scientists currently being trained at the APS will accomplish things during their careers that we haven’t even given thought to. Therefore, based on the enormous impact the APS has had on my career, I see investing my time on the APSUO as a way of “paying forward” to assure that generation that a strong and vibrant APS will exist for them.
