R. M. Suter Research Group
High Energy X-rays Applied to Microstructure Science
The Suter research group in the Department of Physics at Carnegie Mellon University develops and applies novel, non-destructive, three dimensional, x-ray microscopies (notably High Energy Diffraction Microscopy or HEDM) that focus on meso-scale structural responses in polycrystalline materials. Measurements are performed at the Advanced Photon Source at Argonne National Laboratory and high performance computing is used to process terra-byte scale data sets, identify salient features, and track responses over multiple states of samples. The microscopies provide the opportunity for many “first of their kind” experiments as well as systematic, in-situ studies of materials evolution. Observations include thermal evolution and mechanical deformation responses under a wide variety of conditions; sophisticated sample environment hardware has been and continues to be developed. Materials studied range from elemental metals to complex industrial alloys and ceramics. The data sets yield unique opportunities to test and develop computational models of materials responses. Reliable and predictive models based on experimental observations are essential for the goals of, for example, the Integrated Computational Engineering of Materials paradigm and the Materials Genome Initiative. We collaborate with researchers at academic institutions, industrial laboratories, and Department of Energy and Department of Defense laboratories. Graduate students and post-doctoral associates are sought for and have taken employment in all of these types of institutions.

Notice: We are currently accepting applications for an open post-doctoral associate position. Funds are currently available and an excellent candidate can start as soon as they are available. Below is a brief description of the project and position; inquiries can be sent to Suter.
Candidates should have experience with synchrotron x-ray diffraction methods, computational analysis of large data sets, and the ability to work in a collaborative environment. Knowledge of programming in Python is desirable. A Ph.D. in Physics, Materials Science, or a related discipline with a significant experimental component is a prerequisite. The successful candidate will join a collaborative team at Carnegie Mellon, the Advanced Photon Source and additional collaborators at other laboratories.
