PostDoc positions

We currently have the following open positions:

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).

MRI Staff scientist/PostDoc for UHF MRI at the EPFL

Located at the beautiful Lake Geneva, Switzerland, the Center for Biomedical Imaging (CIBM) is the result of a major research and teaching initiative between universities and hospitals, namely the Université de Genève (UniGE), the Université de Lausanne (UNIL), the Ecole Polytechnique Fédérale de Lausanne (EPFL), the Centre Hospitalier Universitaire Vaudois (CHUV) and les Hôpitaux Universitaires de Genève (HUG). Its overall goal is to foster state-of-the-art biomedical imaging applications to further advance research and technological development. The Center’s Animal Imaging Technology core (AIT) concentrates on the following equipment:

  • 7 Tesla MRI system (Siemens, dedicated to human brain)
  • 9.4 Tesla horizontal bore MRI system (rodents)
  • 14 Tesla horizontal bore MRI system (rodents)
  • Two hyperpolarizers

The facility has further access to 3T research scanners (Siemens), EEG, Micro-PET and avalanche-photodiode PET scanner as well as a signal processing unit (see also

In this context we are looking for a
