||Exploring the variability of connectivity-based parcellation of the cerebral cortex
Postdoc position in Neurospin, Paris area, France
Subdividing the cerebral cortex into meaningful parcels is a hallmark of modern neuroimaging that can be tackled from a variety of imaging modalities.
For the last 20 years, the image analysis lab of Neurospin has been developing techniques to map fiber bundles from diffusion MRI.
More recently, the resulting tractograms have been used to perform complete parcellations of the cortical surface using connectivity-profiles, which can be achieved at the level of each individual with a population-based consistency.
Applications are invited to explore the meaning of the variability of the resulting parcellations at the scale of the massive datasets of the HCP (1200) and UKbiobank (100000) projects.
The successful candidate will have access to High Performance Computing centers, for which the current toolbox called Constellation (BrainVISA) will have to be adapted.
This work will be performed in collaboration with other groups of the Human Brain Project consortium, including the VirtualBrain (https://www.thevirtualbrain.org).
Commitment is expected for a year, with a possible extension of up to 3 additional years, in the context of the HBP (https://www.humanbrainproject.eu/en/).
The position is open to candidates with a background in data/image processing and/or high performance computing.
A solid background in Python and C++ is mandatory.
Experience in neuroimaging is a plus, but not required.
A record of peer-reviewed journal publications is strongly recommended.
Research Center – Neurospin is located in the suburb of Paris.
It is a multidisciplinary neuroimaging research center gathering about 180 research fellows with a wide variety of research programs (MR physics, computer science, cognitive neurosciences, clinical research, etc.).
For instance, the physicists at the origin of the CERN magnets, are developing an Extreme High Field 11.7 MRI for humans.
While this outstanding scanner is a flagship, the center hosts multiple other instruments, which is leading to a sparkling research ecology that allowed Neurospin to be the nest of Scikit-learn (http://scikit-learn.org/), one of the most famous machine learning software.
