PhD position in Synchrotron based X-Ray Microscopy – DTU Physics

Updated: about 2 months ago

During the last 10 years we have developed an X-ray microscope at the European Synchrotron Radiation Source (ESRF) in Grenoble, France, that can acquire movies of how the internal structure of crystalline materials (grains, domains, defects) evolve during processing – inside mm sized samples, in situ and in 3D. In our center: “The physics of metal plasticity” we use this microscope to visualize the selforganization of dislocations and domains when deforming the material. We use the experimental movies to guide and optimise 3D materials simulations. In this way we can reveal the physical mechanisms governing the basic mechanical properties, such as strength. 

We are looking for an outstanding and motivated candidate to join our interdisciplinary and international group, where we combine X-ray physics, simulations of experiments and scientific computing with dislocation dynamics simulations. Based at the Technical University in Denmark you will be working closely with beamline scientists at ESRF and your modelling oriented colleagues at DTU and in the US. You will also be part of a Danish Center-of-Excellence on hard materials in 3D, SOLID, where you will interact with 15 other PhDs and post docs, all exploiting the latest 3D methods based on large scale x-ray and neutron facilities, within a broad range of fields.

As a PhD, your mission is to conceive, develop and implement x-ray microscopy studies of the microstructure of metals. This will involve experiments, complex data analysis and interpretation of results. As the instrument is first-of-its-kind, there are many possible avenues for the PhD study.

You are excited about experimental science and advanced data analysis, and we expect that you enjoy being part of a team, that you have sense of humor, is a good problem solver and that you can work efficiently and independently.

For this position we favor candidates with a degree in physics or materials science. You should

  • Have a solid grasp of diffraction, solid state physics and linear algebra
  • Be skilled in data analysis with proven experience with programming, e.g. Python
  • Be skilled in experimental work

Previous experience with synchrotron based science or TEM or materials microstructures is an advantage but not required.

You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU's rules for the PhD education .   

The assessment of the applications will be made by Professor Henning Friis Poulsen, DTU Physics and Professor Grethe Winther, DTU Civil and Mechanical Engineering.

We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility.

Salary and appointment terms
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union. The period of employment is 3 years.
