Employeur

The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas: defence and security, low carbon energies (nuclear and renewable energies), technological research for industry, fundamental research in the physical sciences and life sciences.​

Within LETI, the Systems Department (DSYS) designs, implements and integrates innovative system functions for industrial, consumer, scientific, space, security or defense applications that use emerging or newly emerging technologies, micro-and nanotechnologies, but also skills, know-how and technologies relating in particular to: radio transmissions, telecommunications, antennas and antenna systems, system and component safety, sensors / actuators and electronic sensors, sensor systems and networks, analog and digital electronics and associated signal and information processing, magnetometry, metrology and the exploitation of weak magnetic fields, remote power, recovery and energy management.

Poste et missions

Our lab works on optically pumped magnetometers (OPM) based on helium-4 metastable atoms. Our main achievement in last years has been the design and space qualification of the most advanced OPMs available for spatial exploration, which were launched on ESA Swarm mission [1].

With this very same species we have developed OPMs for medical imaging of brain (magneto-encephalography – MEG) and heart (magneto-cardiography – MCG), which have the advantage of operating at room temperature, with no heating or cooling. The development of these two imaging techniques is an opportunity to better understand and diagnose pathologies like epilepsy, Alzheimer or arrhythmia.

 

A few years ago we performed proof of concept measurements of both MCG and MEG with primitive versions of our sensors [2,3]. After getting a better understanding of our sensors physics [4] and implementing substantial improvements, we are now developing arrays of OPMs and collaborating with several clinical teams in order to test them for different applications and environments.

 

The purpose of this post-doctoral position is to contribute to the development of magnetometer arrays. It involves mainly the deployment of OPM arrays in the clinical environments where they are going to be tested by several of our partner medical research teams in both neurology and cardiology. The post-doc should be able to deploy and operate the sensors in these environments, solve the practical issues, and bring feedback on all kind of improvements that are needed. He or she will also participate in the implementation of some of these improvements, and their tests in lab environment.

This work is aimed at bringing this technology to the medical imaging market, in collaboration with a start-up currently prepared by CEA-Leti. It will be carried out in a multidisciplinary team, composed of researchers, experienced engineers, as well as PhD students and post-docs.

Profil

The applicant should hold a PhD on a field related to engineering or neuroscience. He or she should like working with varied teams of both engineers and clinical researchers, in a challenging and fast-paced project. Our lab is well equipped and staff engineers will be available to help the post doc in technical subjects, like sensor electronics. The results of this work will be divulgated in form both of journal publications and of patents.
