We currently have the following open position:
PhD student – Early Stage Researcher (ESR) (f/m)
INSPiRE-MED (Integrating Magnetic Resonance Spectroscopy and Multimodal Imaging for Research and Education in MEDicine)
Title: Maximize metabolic information in a multi-parametric study at ultra-high field, from pre-clinical to clinical validations
This position is one of the 15 ESR positions of the INSPiRE-MED European Training Network, which focuses on the development of Magnetic Resonance Spectroscopy (MRS) and MR Spectroscopic Imaging (MRSI) combined with Positron Emission Tomography (PET), enhanced by machine learning techniques.
The main objective of this study is to maximize the metabolic information in a multi-parametric approach at ultra-high field, from pre-clinical to clinical validations. We will first develop a multimodal MRS(I) approach for maximizing the metabolic content using optimized determination of diffusion proprieties of metabolites combined with optimized sequences for specific metabolites and macromolecules detection, with proton (1H) and hetero-nuclear MRS (31P) at high field. We will then evaluate the benefits of improved multimodal MRS in clinical and pre-clinical applications: extension of diagnostic evaluation from tissue structure characterization to changes in brain metabolites at macro- and micro-scale.
This project is hosted by the Centre for Biomedical Research (CIBM). CIBM is involved in the INSPiRE project and is particularly known as a world leader in development and implementation of high field MRI/MRS of the brain. This center is the result of a major research and teaching initiative of the partners in the Science-Vie-Société (SVS) project, namely the Université de Genève (UniGE), the Université de Lausanne (UNIL) and the EPFL, as well as the corresponding University Hospitals, the Centre Hospitalier Universitaire Vaudois (CHUV) and les Hôpitaux Universitaires de Genève (HUG). The candidate will be part of a team composed of several PhD students and experienced researchers involved in developing new MR methodologies and doing exciting applications of MR spectroscopy and imaging on humans and rodents.
The selected candidate will be able to take advantage of the unique set-up of the INSPiRE-MED network, encompassing 12 academic and 9 industrial partners providing the young researchers with transferable and generic skills as well as a comprehensive, wide-ranging education on the basic principles of medical imaging and image analysis. This multi-disciplinary environment encompasses physics, mathematical and computer sciences, with applications in medicine and biological sciences.
You should have a master’s degree in physics, biomedical physics, computer science, or a similar degree with an equivalent academic level. A genuine interest in magnetic resonance techniques, magnetic resonance spectroscopy data processing and research should motivate your application. Previous experience in MRI/MRS and programming skills (e.g. matlab) will be a plus. The candidate should be fluent in English and have strong social abilities allowing an active participation to the European network, fruitful exchanges with other students and researchers, and an excellent integration in the team of your research group. You should be ready and able to travel in Europe for the network meetings as well as for sharing the experience of your secondment team.

Advanced super-resolution reconstruction methods for quantitative magnetic resonance imaging of the developing fetal brain
Location: This project will take place in the Center for BioMedical Imaging (CIBM) and the Department of Radiology at the Lausanne University Hospital (CHUV) and the University of Lausanne (UNIL) in Switzerland.
Start date: January 2019 (roughly)
Project description: Today, there is an increasing awareness that early brain development has an influence on health later in life. However, the study of brain maturation in vivo is challenging as it involves several complex intertwined processes. Quantitative MR imaging (qMRI) has gained a lot of attention in recent years and was shown to provide sensitive information on subtle changes in brain tissue after birth. Combining this sensitivity with super-resolution techniques adapted to prenatal imaging would allow high-resolution 3D quantitative MR imaging of the fetal brain, presenting a great opportunity to learn and understand more about the processes governing early brain maturation in utero.
The main goal of this project is to develop advanced quantitative imaging techniques for studying the maturation of the human brain in its early stages of development, when it undergoes the most significant changes. To this end, we will conceive and implement new SR reconstruction methods in conjunction with novel segmentation and MR image acquisition schemes. Specifically we will develop (i) an integrated reconstruction and segmentation framework for T2w fetal imaging, (ii) a SR framework for the reconstruction of diffusion MR images (dMRI), and (iii) new qMRI sequences for T1 and T2 mapping of the fetal brain. This project is funded by the Swiss National Science Foundation (SNSF 205321_182602), total duration of 48 months, three research positions are currently available: 2 PhD students and 1 post-doc.
Research environment: This project is hosted at Medical Image Analysis Laboratory (MIAL), lead by Dr M. Bach Cuadra, of the Radiology Department and Center for Biomedical Imaging (CIBM) of the Lausanne University and University Hospital (CHUV/UNIL). MIAL is a group of ~10 engineers with the aim at develop novel image processing methods to allow a more effective use of emerging medical images, balanced between fundamental research aspects of image processing and application-oriented projects. We have access to several state-of-the-art clinical MRI scanners, and we have active collaborations with the CHUV departments of Radiology, Neurology, Neurosurgery, and Cardiology as well as with the ACIT Siemens and EPFL.
This project will be held in collaboration with the Radiology Department at CHUV (lead by Prof. R. Meuli), the MR CHUV CIBM unit (lead by Prof. M. Stuber), Universitäts-Kinderspital Zürich (KISPI), Center for MR-Research (Dr A. Jakab) and ACIT group at Siemens Healthineers Switzerland (lead by Dr. T. Kober).

PhD student – Developing quantitative MRI of the neck for the assessment of stroke risk
Atherosclerosis results in the formation of plaque in the carotid arteries, which can lead to lethal stroke when it ruptures. While surgery and therapy can be used to prevent such rupture, current medical imaging is not specific enough to predict which plaques will rupture. MRI can be used to quantify several rupture risk factors, but not the inflammation severity of the plaque, which is thought to be the most critical risk factor. The goal of this project is therefore to develop a new combined fluorine-19 (19F) MRI and parameter (T1 and T2) mapping technique for the quantification of plaque rupture risk factors: 19F MRI will be used for inflammation mapping, while the parameter mapping will be used for tissue characterization. The project is funded by the Swiss National Science Foundation (SNSF).
You will have two parallel multidisciplinary projects that focus on MRI of the neck. In the first you will develop and validate a new 3D motion-resolved parameter mapping technique, while in the second project you will optimize the performance of 19F MRI in the clinical setting. These projects will involve programming MRI pulse sequences in Matlab and C++, mathematical optimization and image reconstruction, as well as scanning phantoms and healthy volunteers. Once both techniques have been optimized, they will be validated in a clinical trial with patients that will undergo plaque removal surgery (endarterectomy) to avoid stroke.
The position is available immediately; a PhD program will normally take 4 years to complete.
This PhD project will take place in the Center for BioMedical Imaging (CIBM) and the Department of Radiology at the Lausanne University Hospital (CHUV) and the University of Lausanne (UNIL) in Switzerland. You will be part of a group of ~15 engineers and physicists that is embedded in the hospital. The group has access to 4 state-of-the-art clinical MRI scanners, and has active collaborations with the Departments of Neurology and Cardiology as well as the research department of Siemens.
We are looking for highly motivated candidates with a Master’s degree in engineering, physics, life science or a similar degree, preferably at ease with programming and applied mathematics.
