Postdoc position in experimental materials physics: Quantitative X-ray computed tomography (CT) studies of mesoscale structures in soft, biological and porous materials

A Postdoc position is available at the Department of Physics. The position is financed by NTNU. The appointment has a duration of 3 years.

Information about the Department

The position is organized in the Department of Physics. Currently, there are 27 professors, 10 associate professors, 7 adjunct professors, 70 PhD research fellows and 24 postdoctoral researchers appointed at the Department of Physics. Further information is available at: The Department’s research spans a broad spectrum of natural sciences and technology, which in turn allows us to offer an education that provides a solid basis for future careers. Physics research is carried out in experimental as well as theoretical fields, often across conventional boundaries between disciplines trough external collaborations. The Department’s central research areas are biophysics, nanoscience, surface physics, modern optics, astrophysics, solar energy, materials science, soft matter physics, and medical technology. Research staff at the Department makes a special effort to increase the awareness and understanding of the importance and impact of physics in society.

Job description

The aim of the project is to develop quantitative X-ray computed tomography (CT) methods for analysis of mesostructured soft, biological and porous materials. X-ray imaging and microscopy techniques are rapidly becoming delicate probes of soft functional materials, both using synchrotron and home laboratory equipment. The activity will focus on refining methods for extracting quantitative information (local densities, porosities, tissue orientation, branching of pores/canals, etc.) from multidimensional data obtained using a number of CT modalities (absorption, phase, and scattering contrast) combined with advanced data analysis. Correlation with coherent anti-Stokes Raman scattering microscopy (CARS) will be attempted. Particular attention will be given to porous materials in close collaboration with the newly established Center of Excellence PoreLab, and to biological tissue, notably cartilage structures predisposing for the condition osteochondrosis in piglet joints with partners at the Norwegian University of Life Sciences (NMBU). The work will involve designing and using appropriate experimental measurement schemes. Sophisticated analysis of large datasets, likely using statistical and machine learning methods, will be an integral part of the work.

The three targeted research objectives of the project are: (i) Refinement of high-resolution quantitative 3D X-ray microscopy schemes for studying heterogeneous soft materials; (ii) Development of computer-based analysis approaches for extracting quantitative information; (iii) Efforts towards in situ and low-dose approaches.

In addition, the candidate is expected to participate actively in the group activities with mentoring and co-supervision of students.

The project partners are well positioned for this demanding project with excellent contacts both internationally to leading synchrotron facilities and to relevant Norwegian industries.


The applicant should hold a PhD in physics. In exceptional cases, candidates with a background in related fields like biophysics, nanotechnology, or materials science, can be considered. The position requires a strong background in experimental science and data analysis. Experience from nano-structural studies using scattering, diffraction or microscopy methods is desired. Knowledge of coherent imaging or microscopy (e.g. ptychography or holography) would be considered an advantage. Strong computer programming skills (in e.g. Matlab, Python or C) are desired.

The successful candidate should be creative, ambitious and enthusiastic, with a strong ability to work goal-oriented. Excellence in scientific writing and good oral presentation skills are requested as the candidate will be involved in EU-networking activities. He/she should enjoy interdisciplinary research and take keen interest in learning and working in teams, which is of particular importance in this multidisciplinary project.

The position requires spoken and written fluency in the English language.

Terms of employment

The appointment of the Postdoctor will be made according to Norwegian guidelines for universities and university colleges and to the general regulations regarding university employees.

NTNU’s personnel policy objective is that the staff must reflect the composition of the population to the greatest possible extent.

The position as Postdoc is remunerated according to the Norwegian State salary scale. There is a 2% deduction for superannuation contribution.
