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 (as of 12/2018) accepting applications for two open post-doctoral associate positions. In both cases, funds are currently available and an excellent candidate can start as soon as they are available. Below are brief descriptions of the projects and positions; inquiries can be sent to Suter.
Candidates should have experience in building and applying experimental systems and in automating experiment controls. Knowledge of programming in Python is desirable since that is the language to be used in this highly automated system. Experience operating in a large facility is desirable and in the synchrotron facility environment is highly preferred. A Ph.D. in Physics, Materials Science, or a related discipline with a significant experimental component is a prerequisite. The successful candidate will be a part of a highly interactive development team and should be comfortable working in such an environment.
