Vacant job

Lund University was founded in 1666 and is consistently ranked among the world's leading universities. There are approximately 46,000 students and 8,500 employees in Lund, Helsingborg, and Malmö. We are united in our strive to understand, explain, and improve our world and the conditions of people.

Description of the activity

You will be enrolled at the Department of Synchrotron Radiation Research but will be actively involved in the operation of the MicroMAX beamline within the RÅC-funded MIRA project.

The Department of Synchrotron Light Physics (http://www.sljus.lu.se (http://www.sljus.lu.se)) is part of the Department of Physics and has more than 40 employees. The focus of the research is experimental studies of the electronic, structural, and chemical properties of materials. At the department, we use and develop a wide range of synchrotron and lab-based techniques. We are also involved in developing beamlines, experimental stations, experimental techniques, and accelerator systems for the MAX IV laboratory, and we have a close connection with the European Spallation Source (www.esss.se (www.esss.se)), a new European neutron facility under construction adjacent to MAX IV. MAX IV is a national large-scale laboratory that is part of Lund University and is within cycling distance from the Department of Physics. The laboratory is the world's most brilliant synchrotron light facility, where researchers from Sweden and the rest of the world conduct research in fields such as materials science, biology, chemistry, and nanotechnology.

NanoLund (http://www.nano.lu.se (http://www.nano.lu.se)), formerly known as the Nanometer 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 doctoral students and researchers within the faculties of Engineering, Science, and Medicine at Lund University. The vision is to bring together the most creative minds in a world-leading interdisciplinary research environment to contribute to solving society's major challenges by pushing the boundaries of nanoscience. NanoLund operates Lund Nano Lab (http://www.nano.lu.se/lundnanolab-2 (http://www.nano.lu.se/lundnanolab-2)), which has excellent facilities for manufacturing and characterization at the nanoscale.

Being a Doctoral Student

As a doctoral student, you are both admitted as a student and employed at Lund University.

As a research student, you are trained in a scientific approach. This can be briefly described as gaining practice in thinking critically and analytically, solving problems independently using appropriate methods, and developing research ethics awareness. Additionally, doctoral students are given the opportunity to work on projects, develop leadership skills, and enhance pedagogical abilities. Throughout your studies, you are guided by supervisors. The doctoral studies conclude with a thesis and a doctoral degree.

More about being a doctoral student at the Faculty of Science can be found at naturvetenskap.se.

Subject and Project Description

Beam-steering ptychography is an emerging method for coherent X-ray imaging where the illuminating probe is scanned over the sample by steering the beam, rather than by mechanically moving the sample. This decouples the scanning from the sample's movement and enables high-resolution quantitative 2D and 3D imaging of samples that are difficult to scan mechanically—including soft biological tissues and disease models studied in their native or near-native state.

Within the RÅC-MIRA project, we are seeking a doctoral student who will contribute to the next phase of this development. The work will focus on refining the forward model for beam-steering ptychographic reconstruction and extending the method to 3D via (co-)ptycho-tomography and AI-assisted reconstruction methods, with the goal of improving efficiency and reducing the experimentally required beam time and dose. The position is located at Lund University with research activities at MAX IV (the MicroMAX beamline) and is embedded in close collaboration with DESY (Hamburg) and other partners within RÅC-MIRA. Depending on background and interests, the work may also include experimental activities at synchrotron beamlines and contributions to instrument development.

• General study plan for doctoral education

Job Responsibilities

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

• Develop forward models and reconstruction methods for beam-steering ptychography.
• Work with ptychographic tomography and AI-assisted 3D reconstruction methods.
• Validate algorithms with both simulated and experimental data.
• Contribute to the development of scientific software for large-scale imaging problems.
• Participate in synchrotron experiments together with project partners.
• Work in international research collaboration environments.
• Publish in peer-reviewed journals and present at scientific conferences.

The main task for a doctoral student is to pursue their doctoral education, which includes participation in research projects and doctoral education courses. The job responsibilities may also include participation in teaching and other departmental activities, however, this is limited to a maximum of 20% of working time.
