role in the project

Professor Olivier Bonnot will lead the French participation in the VOICE project and coordinate implementation activities in France. He will oversee the adaptation of the intervention to the French context, support recruitment and engagement of schools and stakeholders, and contribute to the co-design of referral pathways linking education, healthcare, and social services. He will lead the French evaluation activities and contribute to the interpretation of findings, dissemination of results, and development of recommendations for sustainable access-to-care models for children and adolescents exposed to adverse childhood experiences (ACEs) and trauma-related distress.

general expertise and its relevance for the project

Olivier Bonnot brings extensive expertise in child and adolescent psychiatry, vulnerable populations, and integrated mental healthcare pathways, with a particular focus on improving access to care for children and young people with complex neurodevelopmental and psychiatric conditions. His clinical and research work addresses inequalities in healthcare access, coordination between healthcare and social care actors, and the development of patient-centered and multidisciplinary care models.

Within the VOICE project, his expertise will contribute to understanding barriers to care for vulnerable populations, strengthening stakeholder engagement, and supporting the development of more inclusive and accessible care pathways. His experience in multidisciplinary and international collaborations will support the project’s system-oriented and patient-centered approach to improving access to care across different healthcare contexts.
