Postdoctoral Fellow in X-ray imaging and scattering

Postdoctoral Fellow in X-ray imaging and scattering

The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of future technologies, energy and climate, health innovation and fundamentals of nature. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations.

Therefore, about one quarter of our staff are post-docs, post-graduates or apprentices. Altogether, PSI employs 2300 people.

The Structure and Mechanics of Advanced Materials Group at PSI, part of the Center for Photon Science, develops methods and quantitative approaches to investigate nano- and microstructural features across soft matter, biological tissues, as well as metals and alloys. Our work combines X-ray and neutron scattering, diffraction, and imaging, in close collaboration with beamline teams at SLS and SINQ. The postdoctoral fellow will work closely with the Coherent X-ray Scattering Group (CXS) at the cSAXS beamline  this, we are looking for a

• Investigate mineralized biological tissue (such as bone) with small-angle X-ray scattering (SAXS) tensor tomography
• Develop correlative multi-scale analysis pipelines integrating SAXS tensor tomography and high-resolution X-ray tomography, and complementary electron microscopy data (in collaboration with microscopy experts)
• Plan, perform, and analyze experiments at the cSAXS beamline and contribute to improvements in experimental control and automation
• Participate in user support at the cSAXS beamline
• Publish results in scientific journals and present findings at international conferences

• PhD degree in physics or similar natural science discipline, signal/image processing, or engineering
• Interest in interdisciplinary research at the interface of biology, computational tools, and X-ray methods
• Experience with experiments at large-scale user facilities (e.g., synchrotrons or neutron sources) and scientific programming in Python are considered assets
• Motivation to work hands-on at the beamline and contribute to user support activities We offer

  Our institution is based on an interdisciplinary, innovative and dynamic collaboration. You will profit from a systematic training on the job, in addition to personal development possibilities and our pronounced vocational training culture. If you wish to optimally combine work and family life or other personal interests, we are able to support you with our modern employment conditions and the on-site infrastructure.

  Your employment contract is limited to 2 years, with the possibility of extension.
