The centre

Our mission

CRESS is an internationally renowned centre for Research in Epidemiology and Statistics.

Our mission is to study and understand population health and its determinants across the lifecourse (from conception to ageing), develop innovative methods, design and evaluate interventions to improve clinical practices and public health policies.

Our values

CRESS aims to create a dynamic and stimulating environment promoting:

  • Scientific excellence and innovation to meet public health challenges
  • Collaboration, because we believe in the power of collective intelligence
  • Interdisciplinarity to seize the opportunities offered by technological developments and develop new approaches
  • Robust, transparent, reproducible, open and sustainable research through a culture of evaluation and continuous improvement of our research practices
  • Research rooted in real life through strong links with society, patients, hospitals and public health stakeholders
  • Research that has a significant impact, influencing clinical practices, research practices and national and international healthcare policies.
  • Diversity, by attracting talents from a wide range of backgrounds and areas of expertise.
  • Training of future leaders in Epidemiology and Statistics to ensure the continuity and influence of CRESS.
  • Well-being and fulfilment of our members, essential factors in cohesion, creativity and quality of our research.

The CRESS is also the first center to have obtained an International Associated Laboratory (LIA) with an American university, Columbia University: LIA Columbia University / Inserm (Philippe Ravaud, Moïse Desvarieux)

The SMART platform (Shared Research Support Service)

The SMART, led by Stéphanie Chardon, general secretary, is structured around 4 axis:

  • Finance: Carine Suku
  • Human Resources: Sophie Pennec
  • IT: Soraya Aakki
  • Regulations and SNDS: Layla Vazifeh

The Executive Committee (COMEX)

The Executive Committee is composed of the director, the general secretary and all the team leaders. It meets every month.

It ensures that the Centre operating rules are respected and decides on scientific orientations, the arrival of new teams, the creation or arrival of emerging teams, applications for positions and the use of budget from research institutions.

Piloting groups

Our strategy is supported by piloting groups led by a CRESS member appointed by the centre director for a renewable 2-year period.

The Centre Council

The Council is made up of the Executive Committee and elected staff representatives (tenured and non-tenured): engineers, technicians, administrative staff, researchers, and doctoral students. Elections are organised by the general secretary every 5 years. The Council has an advisory role on issues and decisions concerning the Centre’s human, financial, material and property resources.

General Assembly

The General Assembly comprises all the Centre’s staff. A meeting is organised by the director and the general secretary once a year.

The International Scientific Advisory Board (iSAB)

The iSAB is responsible for making suggestions for the Centre’s overall scientific strategy. It meets every two years.

CRESS membership

New members of the CRESS are welcomed into the CRESS community; they sign the CRESS charter highlighting our values, good practices, rules of confidentiality, rights and duties.

Our history

The CRESS was created in 2014 at the instigation of Inserm to have a critical mass of research of excellence in Epidemiology and Statistics within the Community of Sorbonne Paris Cité universities.

Led by Professor Philippe Ravaud for 10 years, CRESS has experienced significant growth with the arrival of 2 teams in 2015 and 2 teams in 2019.

Renewed in 2019, the CRESS has 9 teams and more than 350 members. It depends on the Université Paris Cité. It is one of the largest labeled research centers dedicated to research in epidemiology and statistics in France.

Its national and international influence is the result of the excellent quality of its teams, its scientific production, the impact of its research and its involvement in research training for future talents in epidemiology and statistics.
