On 18 September, Bordeaux will host the first international conference of the Exposome Booster Program
on the theme ‘social inequalities and Exposome’, an initiative that highlights the programme’s advances and opens the way to new collaborations

The Exposome programme aims to create new scientific collaborations around public health issues.
By encouraging interdisciplinarity, Exposome brings together expertise from different laboratories to carry out work that could not be done alone.

The Exposome programme focuses on three main work areas:

• • • Socio-territorial inequalities in exposure from a national perspective
    • Early exposure to social and chemical stresses: impact on respiratory health
    • Causal inference in large dimensions

This first conference represents a key moment in the structuring of an exposome research network. It will focus on the theme of ‘Social Inequalities and the Exposome’.
The morning will be dedicated to introductory lectures on exposome research, with a focus on concrete work being carried out in France. This will be followed by a presentation of the Exposome programme’s structuring projects, in the afternoon, before concluding with a discussion of future challenges and European prospects for this emerging research theme.

The following day, from 9 a.m. to 12.30 p.m., there will be a  workshop “Causal Inference in High-Dimensional Setting”.
As a follow-up to this event, this workshop will look at concrete examples of :

• • • a presentation of the types of problems encountered when analysing exposome data, covering a wide range of factors measured (biological, chemical, social, etc.)

• • • statistical methods for high-dimensional causal analysis relevant to this task

• Sign up
• Date and time: 18 September 2025 from 9am to 6pm
• Location : Bordeaux, France (Campus Carreire – Université de Bordeaux – Amphi Louis – ISPED)
• 19 September 2025 workshop“Causal Inference in High-Dimensional Setting”
