Doctoral student position in MHz 3D X-ray imaging

Lund University, Faculty of Science, Department of Physics

Lund University was founded in 1666 and is repeatedly ranked among the world’s top 100 universities. The University has 40 000 students and more than 8 000 staff based in Lund, Helsingborg and Malmö. We are united in our efforts to understand, explain and improve our world and the human condition.

The Faculty of Science conducts research and education within Biology, Astronomy, Physics, Geosciences, Chemistry, Mathematics and Environmental Sciences. The Faculty is organized into nine departments, gathered in the northern campus area. The Faculty has approximately 1500 students, 330 PhD students and 700 employees.

The Department of Physics is with a staff of about 350 scientists and educators one of the largest departments within Lund University. There are seven research divisions and a number of research centra within the department. The research activities at the department cover a broad spectrum of modern physics.

The Division of Synchrotron Radiation Physics (www.sljus.lu.se) is a part of the Department of Physics and has more than 50 employees. The focus of the research is experimental studies of electronic, structural and chemical properties of materials, accelerators for Synchrotron radiation and instruments and methods for Synchrotron radiation. At the Division we use and develop a wide range of Synchrotron- and lab-based techniques, such as X-ray photoelectron spectroscopy/imaging and X-ray diffraction/imaging. We also host one of Sweden’s largest facilities for scanning probe microscopy. We are additionally engaged in the development of the MAX IV Laboratory in the fields of beamlines, experimental stations, techniques for Synchrotron radiation and the accelerator systems.

NanoLund (http://www.nano.lu.se), formerly known as the Nanometer Structure Consortium, founded in 1988, supports and coordinates activities within nanoscience and nanotechnology at Lund University. NanoLund is today Sweden’s largest research environment for nanoscience, engaging approximately 250 PhD students and scientists in the faculties of engineering, the natural sciences, and medicine at Lund University. Its vision is to bring together the most creative minds in a world-leading interdisciplinary research environment to help overcome society’s grand challenges by pushing the frontiers of nanoscience. NanoLund runs Lund Nano Lab (http://www.nano.lu.se/lundnanolab-2), a state of the art facility for nanofabrication.

Work duties

X-rays have a unique ability to investigate samples in their natural state, such as cells, proteins in solution or electronic devices potentially at resolutions up to the atomic level. The advent of diffraction-limited storage rings (MAX IV) and X-ray free-electron lasers (European XFEL) has opened a whole new spectrum of applications due to their unprecedented brilliance. This project aims to develop a novel X-ray imaging method, christened X-ray multi-projection imaging, capable of filming processes in 3D, with temporal resolution several orders of magnitude faster than up-to-date 3D X-ray imaging techniques. In particular, the candidate will work on the development of such technique and its application to the study of cellulose fibers, a renewable biomaterial, which can replace fossil-based materials.

The project is experimental with a computational component. The successful candidate will have the opportunity to:

  • participate in developing a novel X-ray imaging technique that exploits the unique capabilities of MAX IV and the European XFEL.
  • Perform experiments on novel biomaterials (cellulose fibers) and address fundamental questions to replace plastics.
  • Develop novel algorithms to process and analyze the data collected with XMPI

The main duties of doctoral students are to devote themselves to their research studies which includes participating in research projects and third cycle courses. The work duties can also include teaching and other departmental duties (no more than 20%).

Admission requirements

A person meets the general admission requirements for third-cycle courses and study programmes if he or she:

  • has been awarded a second-cycle qualification, or
  • has satisfied the requirements for courses comprising at least 240 credits of which at least 60 credits were awarded in the second cycle, or
  • has acquired substantially equivalent knowledge in some other way in Sweden or abroad.

A person meets the specific admission requirements for third-cycle studies in Physics if he or she has:

  • passed an independent project (e.g.degree project) of at least 30 credits in a relevant subject

Equivalent knowledge acquired through corresponding programmes will be assessed individually. In order to enable interdisciplinary initiatives and important specialisations in certain areas, students with qualifications in subjects other than Physics may be considered for admission.

Finally, the student must be judged to have the potential to complete the programme.

Additional requirements:

Very good oral and written proficiency in English.

For the present position, additional assessment criteria that are appreciated are:

  • Experience in programming: Python, MATLAB, or C++
  • Experience in imaging techniques in any part of the electromagnetic spectrum
  • Experience in machine learning and big data
  • Experience in 3D imaging and 3D reconstructions is appreciated
  • Experience in instrumentation and controls
  • Experience in wave-propagation, simulation, and phase reconstruction is appreciated

Basis of assessment

Selection to postgraduate studies is based on the expected ability to perform well in the studies. The evaluation of the ability to perform well is based primarily on the results of studies at the basic and advanced levels, in particular:

  • Knowledge and skills relevant to the thesis project and the subject of the study.
  • An assessment of ability to work independently and to formulate and tackle research problems.
  • Written and oral communication skills
  • Other experience relevant to postgraduate studies, such as professional experience.

Consideration will also be given to good collaborative skills, drive and independence, and how the applicant, through his or her experience and skills, is deemed to have the abilities necessary for successfully completing the third cycle programme.

Terms of employment

Only those admitted to third cycle studies may be appointed to a doctoral studentship. Third cycle studies at LTH consist of full-time studies for 4 years. A doctoral studentship is a fixed-term employment of a maximum of 5 years (including 20% departmental duties). Doctoral studentships are regulated in the Higher Education Ordinance (1993:100), chapter 5, 1-7 §§.

Instructions on how to apply

Applications may be written in English or Swedish and include a cover letter stating the reasons why you are interested in the position and in what way the research project corresponds to your interests and educational background. The application must also contain a CV, degree certificate or equivalent, and other documents you wish to be considered (grade transcripts, contact information for your references, letters of recommendation, etc.).

Lund University welcomes applicants with diverse backgrounds and experiences. We regard gender equality and diversity as a strength and an asset. We kindly decline all sales and marketing contacts.
