CNRS Physics

To understand more about the world around us, researchers working in the laboratories of CNRS Physics combine experiment, theory and modeling. Their work includes the development of cutting-edge instrumentation and the creation of new physical objects or concepts. Research conducted at the INP focuses on understanding matter, radiation and their interactions. It has lead to tangible innovations and demonstrates modern society's need for basic research.

Basic research in physics: understanding nature and addressing societal challenges

CNRS Physics administers over 70 laboratories and works to structure its various scientific communities. Its research covers a vast disciplinary field: the sciences of matter from the scale of subatomic particles to solids, radiation and all its interactions with matter, as well as the fundamental laws governing the physical world.

Research ranging from fundamental physics to interdisciplinary science

Physics has a very broad field of applications. This ranges from elementary particles to cosmology and from matter to waves. It also extends as far as micro- and nano-technologies, as well to chemical and biological processes. Physics is defined not only by the object of study but also by the approach, method and tools used. The INP strongly encourages interdisciplinary research with solid roots in its core subjects, an essential ingredient for a successful cross-fertilization of ideas. Thus, physicists design methods and tools (instruments, software and theoretical approaches) which go on to be used by communities working in other disciplines.

A community of over 6000 people

The INP federates scientific communities to work on ambitious targeted projects via the research structures that it oversees:

  • 75 research and service units
  • 10 research federations
  • 25 research networks

These structures bring together CNRS researchers, technicians and engineers, along with research and support staff from the stakeholders with whom the CNRS jointly manages its laboratories. These are mainly universities and other research organizations such as the French National Institute of Health and Medical Research (INSERM) or the French Alternative Energies and Atomic Energy Commission (CEA). In total, in terms of personnel this represents:

  • 3,500 researchers and academics (including 1,220 from the CNRS)
  • 1,620 engineers and technicians (including 1,030 from the CNRS)
  • 1,820 PhD and postdoctoral fellows

A beacon of top-level research

Physics contributes to the progress and reputation of all French sciences at the highest international level. The fourteen Nobel Prize awards to French physicists testify to this. The last three were awarded to: Albert Fert in 2007 for his discovery of giant magnetoresistance and his contribution to the development of spintronics; to Serge Haroche in 2012 for the development of pioneering experimental methods enabling the measurement and manipulation of individual quantum systems; and to Gérard Mourou in 2018 for the development of a method for generating ultra-short, high-intensity optical pulses.

A significant international presence

Currently, two thirds of the INP's scientific publications result from international collaborations. The international visibility of the INP is based on coherent international partnerships, particularly in Europe, Canada, Japan, the United States, Latin America, Russia, China and Singapore. This has led to several forms of collaborative structures including:

  • 3 International Research Laboratories,
  • 21 International Research Projects,
  • 12 International Research Networks,
  • 58 International Emerging Actions.

An active innovation strategy

The INP is committed to promoting research developed in its laboratories. It encourages new partnerships to help satisfy society's need for innovation. It works upstream to detect, evaluate and stimulate the innovative potential of its teams' and units' projects and then supports their initiators in the development and transfer of innovations and of breakthrough technologies.

  • 68 start-ups in operation created by laboratories (cf. http://www.cnrs.fr/en/innovation)
  • 45 patents filed per year
  • 16  joint research structures with companies (cf. http://www.cnrs.fr/en/innovation)

A significant scientific production

The publication of the results of their work is critical for physicists.  It is the first step in the dissemination and the transfer of their basic research and leaves a lasting trace of their work. The main objective of publications is for them to be read, compared with other results, and then to have their subjects taken further.

  • 7500  publications annually (15% of CNRS production, 6% of world physics production),
  • 60% of publications are interdisciplinary and jointly written with members of other Institutes - 16% with the Institute of Chemistry (INC), 20% with the Institute for Engineering and Systems Sciences (INSIS),
  • 40% of the INP's publications cover themes other than physics. This is a strong indicator of the interdisciplinarity of the research carried out in the Institute's laboratories.

Gender parity and professional equality between women and men

CNRS Physics is taking action to foster gender parity and equality on a daily basis in laboratories and to encourage young women to pursue careers in the field of physics. CNRS Physics has made this topic a priority by establishing a gender parity and equality team responsible for monitoring and implementing relevant measures. The work of our female researchers, lecturer-researchers, PhD students, engineers, and technicians is highlighted, along with best practices from CNRS Physics laboratories and the CNRS in this field. An annual training course has also been created to support women in their career paths within CNRS Physics laboratories.

CNRS Physics' Gender Parity and Equality Policy

The gender equality policy of CNRS Physics is part of the broader parity policy framework of CNRS. In this context, the institute has implemented a plan to improve gender parity and equality in its laboratories, with two main objectives:

  1. Increase the number of women entering physics laboratories
  2. Ensure that gender does not influence professional activities or career advancement

Preamble: Some Observations...

The CNRS Physics gender parity and equality policy was developed based on the following observations:

  • Women are underrepresented in physics laboratories, and the number of young women choosing careers as physicists remains low.
22,5% Female researchers (2023)
21% CNRS Female senior researchers (2023)
33,1% CNRS Female engineers and technicians (2023)
  • Although the number of women researchers in physics, mathematics, engineering, and computer science is relatively low, their chances of promotion are close to those of men, as shown by the Male Advantage Index. A male index of 1 means that the relative proportion of men promoted to research director is the same as that of women. However, in scientific fields with more female researchers—such as biology, humans and social sciences, and ecology—the Male Advantage Index is significantly above 1 (2023 data, see figure below).
Avantage masculin CNRS 2023
Figure - Proportion de femmes et d'hommes par corps et avantage masculin par institut (graphique issus du Rapport social unique 2023 du CNRS
  • Female and male researchers participate less in training programs than engineers and technicians (IT staff, men and women combined), particularly in human resources training.
     
  • While women often contribute to organizational support within labs, they less frequently hold leadership positions.
     
20% of researchers among trained staff in 2023
12 out of 70 CNRS Physics research and service units are led by women
  • Gender stereotypes (and other biases) remain prevalent in workplaces and labs. Awareness of these biases within decision-making groups (cf. evaluation committees) enables more effective application of parity and equality principles. Measuring gender stereotypes within a unit should help foster greater consideration to gender equality.
     
  • An interruption in professional activity can create a disruption in the working lives of female engineers, technicians and researchers, which needs to be supported (financially and in terms of organization).

How Can Gender Parity and Equality Be Improved in CNRS Physics Laboratories?

 

The CNRS Physics policy to improve gender parity and equality in its laboratories is structured around three main pillars:

  • Attractiveness of the discipline. CNRS Physics aims to increase communication and mediation initiatives to raise awareness among young girls about physics as a viable and engaging career path. Laboratories are strongly encouraged to incorporate these aspects into their public outreach initiatives (e.g., specific training for science outreach). CNRS Physics also actively promotes female physicists' careers through the Institute's communications.

 

  • Laboratory Life. CNRS Physics seeks strong collaboration with laboratories to collectively improve parity and equality. To this end, the Institute proposes to relay, through a network of gender focal points per CNRS Physics unit that has yet to be developed, the actions already in place at CNRS and the tools available to raise awareness of these issues over the long term. (e.g., encouraging CNRS Physics labs to measure gender stereotypes, to follow the e-learning course on ‘gender inequality in research’ developed by the CNRS MPDF; set up specific parity and equality indicators for laboratories, etc.).

 

  • Career Support. CNRS Physics is working to increase the proportion of women in leadership positions and encourages female candidates to apply for such roles. It also seeks to better support women’s careers, particularly after career interruptions such as maternity leave (sharing information on parenting support tools provided by HR departments in the Delegations and Head Office, offering financial assistance to help researchers return from maternity leave, prioritizing secondment requests from female lecturer-researchers returning from maternity leave, exploring funding and support measures to ensure optimal maternity leave conditions for support functions and by offering them specific training (see ANF – "Women in Physical Sciences, to enhance skills, boost self-confidence, and sharing experiences").

 

National Training Program (ANF): “Women in Physical Sciences”

In collaboration with the Île-de-France Shared Training Service (IFSeM), CNRS Physics offers a specific training program titled “Women in Physical Sciences: Enhancing Skills, Building Confidence, and Sharing Experiences.” This is aimed at researchers, engineers, technicians, and administrative staff, providing tools to help them thrive professionally within CNRS Physics laboratories.

Existing Gender Equality Initiatives at CNRS

 

  • Mission for Women's Inclusion at CNRS (MPDF) – Established in 2001, reporting directly to the CEO. It coordinates a network of around twenty regional representatives and works closely with the CNRS Parity and Equality Committee. MPDF acts as a watchdog, providing guidance and evaluation on the integration of gender issues into CNRS’s overall policy.
     
  • Parity and Equality Committee – Composed of representatives from institutes, HR, and MPDF, this committee makes recommendations to CNRS management, which gives them executive force when approved.
     
  • Parity and Equality Coordinator Networks – Some CNRS delegations have created local networks focused on gender equality at their sites. Institutes such as CNRS Physics, CNRS Mathematics, and CNRS Computer Science have also developed their own internal networks. These networks offer a space to share experiences, legitimize parity-related actions, and visibly demonstrate the institute’s commitment to gender equality in laboratories.

Support for Researchers at CNRS Physics

Personalized support is a system designed for researchers at CNRS Physics. It aims to address a professional issue identified either by the individual or by a third party. It is essential that the person concerned is willing to participate in this support. The reason for and content of the sessions are strictly confidential, and anonymity is fully guaranteed.

Support Situations

  • New skills development and career advancement:
    Support when taking up a new post or changing duties, with a need to strengthen and/or develop skills and/or self-confidence building. This also includes exploring new career opportunities.
  • Professional changes and transitions:
    Support during transitional periods, such as internal reorganizations, changes in roles, or returning to work after a prolonged absence (illness, maternity leave, etc.). The goal is to help individuals regain their bearings and find their place in a new or evolving environment.
  • Loss of motivation and questioning the meaning of work:
    Support for individuals experiencing periods of doubt, fatigue, or disengagement in their professional activity, to help them rediscover purpose in their career path and regain lasting motivation.
  • Work-related distress:
    Support for dealing with intense stress, overwork, relationship difficulties, or repeated sick leaves affecting both professional and personal balance. The aim is to better manage these difficulties and restore well-being at work.

This support system complements, but does not replace, other existing forms of support such as training, mentoring, or human resources actions. It also does not substitute systems dedicated to addressing psychosocial risks and conflict situations (support hotlines, incident reporting, mediation, etc.).

Note: This service is limited to CNRS researchers, as separate support systems for research support staff are managed at the regional delegation level.

Mentoring

CNRS Physics places particular importance on the quality of the onboarding process and career support for new staff, especially in the beginning stages, to ensure successful integration and personal development within the workplace community.

Recognizing the diversity of research careers and roles, CNRS Physics is implementing a nationally coordinated mentoring program. Initially, this initiative is available to research fellows who have been appointed within the last five years in its laboratories, as a complement to any local programs.

The CNRS Physics’ mentoring program state of mind

Definition

Mentoring is a relationship in which one person (the mentor) supports and advises a colleague (the mentee), sharing their professional experience and personal insights from similar situations. It is not mandatory or systematic and may involve any early-career researcher.

Le mentorat se distingue du suivi scientifique par la section après le recrutement. Il se distingue aussi des outils mis en place par les laboratoires et les délégations régionales pour l'accueil des entrantes et entrants.

Objectives

Mentoring can address various aspects of professional life, including career development, time management, work-life balance, managing workplace relationships, visibility in the lab or internationally, responding to calls for proposals, etc.

Guidelines

Mentoring is initiated by the mentee and is based on mutual willingness. Although it involves a difference in experience, it does not establish a hierarchical relationship. It is a professional relationship grounded in listening, respect, and trust, with a shared commitment to confidentiality.

Implementation of Mentoring at CNRS Physics

Coordination Committee

A coordination committee composed of individuals from CNRS Physics and its Scientific Steering Committee (CSI) oversees the mentoring activities, including matching mentors and mentees.

At the national level, CNRS Physics has created a pool of experienced professionals who have volunteered to serve as mentors. Each mentoring pair is linked to a reference person from the coordination committee, who can offer additional support throughout the mentoring process.

Forming Mentoring Pairs

Anyone interested in participating in the mentoring program should send a brief request explaining their motivation to the coordination committee at: INP-mentorat@cnrs.fr.

A committee member will then contact the individual to clarify goals and expectations and to propose a suitable mentor. Following this exchange, the mentor and mentee will meet for a first session to discuss the objectives and structure of their mentoring relationship. If both parties agree on the goals and terms of the mentoring process, the mentor-mentee pair is officially established upon signing the Mentoring Charter.

Emeritus Status at CNRS Physics

On the occasion of the publication of a recommendation by its Scientific Council regarding emeritus status, CNRS Physics wishes to reiterate several important points, largely based on the CNRS HR Department’s Emeritus Circular.

Emeritus researchers are retired staff members who hold the status of voluntary collaborators. They do not qualify as permanent researchers, and in particular, they can no longer supervise or lead research teams. Likewise, they can no longer respond to calls for proposals in their own name or by delegation, nor sign partnership agreements.

The continuation of their scientific activities—something CNRS Physics naturally views very positively—may require resources (workspaces, travel funds, access to instruments and other resources) that the laboratory provides for them. However, the allocation of such resources must not come at the expense of active researchers, who take priority. CNRS Physics believes it is up to the laboratory’s leadership to assess the level of support that can be granted to these retired colleagues, who are sometimes distinguished and often still very active, while ensuring that this does not impact the professional development of active researchers, especially early-career scientists.

Finally, CNRS Physics encourages each laboratory to clearly define the rights and responsibilities of emeritus researchers in its internal regulations and to involve the laboratory council in the consultation process when the unit’s leadership is issuing a first emeritus appointment or its renewal.
