Current positions:

Research Director (Nanoscience) in CEA
-
Co-Director of the Joint CEA/NTU Laboratory SCARCE in Singapore
-
Visiting Professor at the Nanyang Technological University of Singapore
Jean-Christophe P. Gabriel now leads an international research group delocalised on both CEA Saclay and Nanyang Technological University. Members of the group in NTU are focussing on developping e-waste recycling process steps. In Saclay, in addition to e-waste recycling, the group also investigate nanomaterials, their synthesis, characterisation, processing and applications.
Research
His group current fields of interest are the following:
- Waste recycling: we are developing tools and processes for impoving various wastes recycling to enable more economically viable waste processing. Our efforts in this field started in 2013 and focussed at the time on an integrated microfluidic lab-on-chip that enables much faster exploration of multidimensional phase diagrams of complex fluids. Such lab-on-chip devices integrate various sensors as well as characterizations methods (such as FTIR in hollow waveguides, or X-ray fluorescence). This work was first funded, from 2013 util 2018, by the advanced ERC project REE-CYCLE (PI = Prof. Thomas Zemb) that aims at developing new rare earth extraction/recycling processes, at least 10 times more efficient that current liquid-liquid extraction processes, where JCG was acting co-PI. Since then, within the SCARCE CEA/NTU joint laboratory in Singapore, we have further developped the microfluidic platform as well as expanded our efforts to other process steps in the recycling of e-waste (Printed Circuit boards - PCBs, plastics from e-wastes), such has:
-
PCBs and PV dismantling and associated electronic component sorting;
-
Physical method based separation;
-
Critical metals recovery and purification;
-
Liquid-liquid and Solid-liquid hydrometallurgical recovery process steps development using the world first microfluidic plateform integrating on line FTIR and XRF.
-
Use of supercritical fluid as a green solvent for e-waste recycling.
-
- Nanomaterials: In our laboratory, we synthesize and characterize low dimensionality materials (0, 1 and 2D), by all means necessary and available (from visual/microscopic observations to the use of synchrotrons for the structural investigations of materials). These materials can often be exfoliated/dispersed in solution leading to some complex/colloidal fluids, exhibiting a very wide range of fascinating behaviors. They can also be integrated into various types of devices, hence the following topic.
- Integration:
- Thanks to the awarded ANR Project 4WATER (12/2017-12/2022) (see video of presentation): we are elaborating new and cheap multi-target chemical sensor arrays for the continuous monitoring of groundwater quality. Using a microelectronic approach, the sensors will be based on functionalized nanomaterials and that will target various ions selected for their relevance as regards the quality of fresh water.
- Thanks to the awarded ANR Project 2D-MEMBA (2022-2025): we integrate nanomaterials for the making of less power-hungry membranes for the purification of water.

CV
Dr. Jean-Christophe P. Gabriel is one of CEA’s Research Director, in the field of Nanoscience. Since September 2020, his French laboratory is located in CEA Saclay with a special focus on 1D and 2D nanomaterials and their applications. He is also currently a visiting Professor at NTU where he serves, since August 2018, as co-director of the NTU Singapore CEA Alliance for Research in Circular Economy (SCARCE), CEA's first joint laboratory outside French territory (comprising ~25 postdocs and Engineers). There he directly co-supervise, together with Prof. Alex Yan Qingyu, a team of ~10 postdocs, PhDs and Engineers in the field of e-waste and Prinited Circuit Board recycling.
He first joined the French Alternative Energy and Atomic Energy Commission (CEA) in 2007 as CEA/LETI institute’s “Beyond CMOS” program manager as well as the business director of the academic - industry Caltech – LETI alliance, which led, years later, to the creation of the Startup Apix Technology.
From 2009 to 2016, he became deputy director of CEA’s Nanoscience program (budget: 1 M€/year), help defining, financing, networking, growing, communicating and prospering seed projects and young researchers. Hence, in this role of scientific project manager, he helped the maturation of TRL=0 ideas, trained young researchers in writing very high impact factor articles (Nature and co), co-invented various technologies, helped on building successful project proposals (ERCs), as well as on the germination and business model definition at pre-seeding round of future startups such as NawaTechnologies, Aledia, cell&soft).
In parallel, from 2013 to 2018, he was co-principal investigator of the REE-CYCLE advanced ERC project (2013-2018), that aimed at developing new rare earth extraction/recycling processes, at least 10 times more efficient that current liquid-liquid extraction processes. In his laboratory in Grenoble, created in 2014, he was developing integrated microfluidic lab-on-chip that enable much faster exploration of multidimensional phase diagrams of complex fluids. Such lab-on-chip devices integrate various sensors as well as characterizations methods (such as FTIR in hollow waveguides, or Xray fluorescence).
Former student at the “Ecole Normale Supérieure” in Paris, he received his Ph.D. (1993), supervised by Dr. Patrick Batail, from University Paris-Saclay (formerly Orsay University) and his Habilitation from Grenoble-Alpes University (Formerly Joseph Fourier University). He completed his PhD training with two postdocs. The first in Risø National Laboratory, Denmark, under the supervision of Prof. Klaus Bechgaard, the second at the Material Research Laboratory a the University of California Santa Barbara, under the mentorship of Prof. Anthony K. Cheetham.
His career is a mixed academic – industrial one. He indeed started his tenured career at CNRS (4 years at Jean Rouxel Institute, IMN, Nantes) followed by 6 years in the Californian startup Nanomix (nano.com), where he was one of the first employee. In this UC Berkeley's spinoff he helped in the technology transfer of nanomaterials, hydrogen storage and carbon nanotubes technologies, helped raised $34 million of venture capital money and with his team was the first to put an integrated nanotube based electronic device on the market (a hydrogen sensor, in 2005). Since he left the company in August 2007, Nanomix has marketed fast electronic diagnostic tools (Ebola, COVID-19 etc.) based on, among others, patents that he co-invented.
Jean-Christophe has published more than ~ 80 papers in international peer reviewed journal and is co-inventor on more than 45 patents and patent applications, dealing with nanomaterials (carbon nanotubes, graphene) applications (sensors, H2 storage) and waste recycling processes.
