DESY

We are seeking two motivated PhD candidates to develop a novel multi-scale imaging method at synchrotron radiation facilities, particularly PETRA III at DESY. Samples, be they biological or from materials science, often have a hierarchical structure that determines their function. It is not feasible to scan the full volume of such samples at the highest desired resolution. Therefore, we require an imaging scheme that acquires relevant features at different length scales and integrates them into a single reconstruction volume. The PhD projects aim to develop and implement this novel local adaptive tomography (LAT) scheme, which will allow us to efficiently measure and reconstruct hierarchically organised samples. To achieve this, we need to improve our understanding of the physical image formation and data recovery processes, among other topics. The advertised positions will focus on these topics. One position is in the "X-Ray Nanoscience and X-Ray Optics" group and the other is in the "Computational Imaging" group. The PhD projects are embedded in the frame of the ErUM data project CmarT.

About your role

• Develop improved physical models of the image formation process in holographic X-ray imaging
• Design and implement reconstruction algorithms for handling large-scale tomographic data from limited field-of-view acquisitions
• Collaborate with beamline scientists to validate and optimize the LAT scheme

About you

• Master's degree in Physics/Mathematics/Computer Science or related subject
• Willingness to familiarise yourself in depth with new topics in the fringe area between algorithm development, high performance computing and experiment
• Willingness to work in teams
• Good knowledge of a programming language
• Good communication skills in English/German

Look forward to a unique working environment on our international research campus. Respectful cooperation and the well-being of our DESY employees are particularly important to us. Gender equality is an important aspect for us. To support work life balance we offer flexible working hours and variable part-time. You will benefit from our family-friendly and collegial atmosphere, our established health management and occupational pension provision. As a public funded employer, we offer you a secure workplace and facilitate your individual career with our comprehensive training and development opportunities. Remuneration is according to the regulations of the TV-AVH. DESY offers its employees a financial supplement for a German job ticket (Deutschland-Ticket) at both locations.

We look forward to receiving your application via our application portal:
