The CNRS Physics Research Networks (GDR)
The Research Networks (GDR) bring together and mobilize research teams from various disciplines, from different CNRS institutes, as well as academic or industrial stakeholders, around original or emerging scientific themes. This page lists the GDRs led by CNRS Physics and outlines their research areas.
A CNRS Research Networks (GDR) connects and unites a scientific community around an emerging, original theme. CNRS Physics initiates GDRs focused on scientific topics that address current fundamental or societal issues. These topics may fall within the core business but can also involve interfaces between physics and other scientific fields. In this respect, transdisciplinary GDR led by CNRS Physics are supported in collaboration with other relevant CNRS institutes.
The main missions of a GDR are to foster a thematic, often multidisciplinary, community; to encourage free access to new partners; to promote collaboration and exchange among scientists within the network of participating laboratories; and to establish scientific projects at national, European, or international levels. Expanding GDR communities to include industrial stakeholders—for instance, through the creation of a "partners' club"—enables mutual enrichment and the identification of shared research topics.
This page presents, in the form of summary sheets, the objectives of each Research Network led CNRS Physics. Beyond describing their research focuses, each summary offers the opportunity for new partners—possibly from other disciplinary fields or non-academic sectors—to contact the GDR and join their mailing lists.

The Horizon 2D and Heterostructures (2D+) research network is a horizontal research network that aims to bring together the French community working on two-dimensional materials and associated low-dimensional systems (van der Waals heterostructures, moiré patterns, twisted systems, nanotubes, 2D–1D and 1D–0D hybrids, etc.). Research topics cover synthesis, characterisation, theory and devices, addressing both fundamental properties and emerging functionalities. In a highly competitive international context, the GDR 2D+ promotes scientific exchange, interdisciplinarity, collaboration and visibility at national and international levels.

AQV | Quantitative Approaches to Life Sciences
The Quantitative Approaches to Life Sciences (AQV) research network was created to consolidate and promote links between communities at the interface between biology and physics. The creation of the AQV GDR was based on two observations: (1) today, a better understanding of living organisms requires quantifying and modelling them and taking into account the laws of physics and chemistry, (2) this approach can only be implemented in an interdisciplinary framework. Beyond importing tools and concepts, it also involves addressing key questions in biology through approaches that combine biology and physics. These advances enable the development of new physical concepts (examples: active matter, physics far from equilibrium, noise robustness, learning in frustrated systems, dynamics of very high-dimensional systems).
