Doctoral Student In Physics With A Focus On The Development Of Novel X-Ray Imaging Methods With Beam-Steering Ptychography And Ai

Lund University, Science Faculty, Department of Physics

Lund University was founded in 1666 and is repeatedly ranked among the world's top universities. The University has around 46 000 students and 8 500 staff based in Lund, Helsingborg and Malmö. We are united in our efforts to understand, explain and improve our world and the human condition.

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

The Division of Synchrotron Radiation Research is a part of the Department of Physics and has more than 40 employees. The focus of the research is on experimental studies of electronic, structural, and chemical properties of materials. The Division is developing a new activity focussing on magnetic properties. At the Division we use and develop a wide range of large facility- and lab-based techniques.

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. MAX IV is a national large-scale research laboratory hosted by Lund University and situated within biking distance from the Department of Physics. It provides scientists from Sweden and the rest of the world with the most brilliant Synchrotron radiation source and instrumentation for research in areas such as materials science, structural biology, chemistry and nanotechnology.

Nano Lund, formerly known as the Nanometer Structure Consortium, founded in 1988, supports and coordinates activities within nanoscience and nanotechnology at Lund University. Nano Lund 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.

Nano Lund runs Lund Nano Lab, a state of the art facility for nanofabrication.

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

As a doctoral student, you will be trained in a scientific approach. In short, you will be trained to think critically and analytically, to solve problems independently using the right methods, and to develop an awareness of research ethics. In addition, you will have the opportunity to work on projects, to develop your leadership and pedagogical skills. Throughout your studies, you will be guided by supervisors.

Doctoral studies end with a thesis and a doctoral degree.

Beam-steering ptychography is an emerging approach to coherent X-ray imaging in which the illuminating probe is scanned across the sample by steering the beam, rather than by translating the sample itself. This decouples scanning from sample motion and opens up high-resolution quantitative 2D and 3D imaging of samples that are difficult to scan mechanically — including soft biological tissue and disease models studied in their native or near-native state.

Within the RÅC-MIRA project, we are seeking a PhD candidate to 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 approach to 3D via (joint) ptycho-tomography and AI-guided reconstruction methods, aimed at improving efficiency and reducing the required beamtime and radiation dose. The position is hosted at Lund University with research activities at MAX IV (MicroMAX beamline), and is embedded in a close collaboration with DESY (Hamburg) and other…
