The Department of Molecular Medicine and Surgery (MMK) is looking for one postdoctoral researchers to join Ass Prof. David Marlevi and his team on sequence development, image reconstruction, and the use of data-driven image analysis for next-generation magnetic resonance imaging (MRI). Based in a clinically integrated, well-established cardiovascular imaging network, you will join a team developing and evaluating methods for improved cardiovascular imaging, using a combination of experimental and clinical studies.
Phase-contrast MRI plays a crucial role in cardiovascular flow quantification, with three-dimensional measurements of time-resolved flow (4D Flow) presenting a unique opportunity to deepen our understanding of cardiovascular hemodynamics. However, challenges like long scan times, motion artifacts, and the trade-off between spatial and temporal resolution remain significant barriers for widespread adoption. The incorporation of advanced image acquisition techniques is starting to fundamentally change what can be analyzed and resolved. Specifically, our larger group has shown that innovations in sequence development to enable high-quality image recovery at higher acceleration factors and at unprecedented spatiotemporal resolutions, opening for new diagnostic paradigms.
Your focus will be on developing novel pulse sequences and accompanying image reconstructions for 4D flow imaging, seeking ways to efficiently image volumetric flow in the heart and large vessels. Making use of our translational team, the methods developed will be evaluated using dedicated on-site MRI scanners and in clinical patient cohorts, serving our overall goal of improving our understanding and use of MRI for next-generation cardiovascular care and to translate novel imaging innovations directly into clinical practice.
We are looking for a highly motivated, creative, and independent researcher with a PhD in MR physics. Solid and documented experience of MRI physics is required, as is expertise in relevant programming languages, primarily C++ and Python. Experience in pulse sequence programming is highly advantageous, in particular in the Siemens IDEA environment including ICE, OpenRecon and FIRE. Experience from human cardiovascular MR imaging and analysis is desired but not required.
Scientific expertise and an ambitious, independent, and problem-solving attitude are highly valued. Excellent communication skills in both spoken and written English are a must, as is the ability to interact and work in a translational team of technical and clinical colleagues on an international level. Emphasis will also be placed on personal competence. The postdoctoral researcher will get the opportunity to co-write grants and articles, supervise students, and take part in career mentorship; all providing an excellent basis for a further career as a project leader in academia or industry.
To be eligible for employment as a postdoctoral researcher, a PhD or a foreign degree deemed to be equivalent to a Swedish PhD is required. This eligibility requirement must be fulfilled at the latest at the time of the employment decision. Completion of your doctoral degree within the last three years is considered an advantage. If there are special reasons, your degree may have been completed earlier.
