About Pasteur Network Courses
Since 2012, the Pasteur Network has offered more than one hundred international theoretical and practical courses. These trainings aim to address scientific and public health priorities, support training for researchers at different career stages, and strengthen collaboration within the Network and with partner institutions. They are open to post graduate students and young scientists from both the Network and national institutions in the host country.
Four young graduates from the Pasteur Network were honored at the Institut Pasteur’s PhD Graduation Ceremony on December 12th 2025. This celebration marked the end of a chapter for this new generation of researchers.
Since 2013, this annual event —organized by the Education Department of Institut Pasteur—has showcased the achievements of young researchers, marking its 13th edition in 2025. The ceremony featured a keynote address by Pr. Myriam Merad, Director of the Institute for Precision Immunology at Mount Sinai School of Medicine. Renowned for his groundbreaking work in the chemical biology of nucleic acids, Sir Shankar shared an inspiring message to young graduates encouraging them to pursue exploration over linear career pathways and take all the competencies learned during PhDs also outside of the laboratories.
Following his speech, Rebecca Grais, Executive Director of the Pasteur Network, formally introduced the PN graduates, emphasizing their contributions to a wide range of research fields. Each laureate also presented the highlights of their PhDs. Doctoral students from the Network had the opportunity to work on a wide variety of topics reinforcing the strength and reach of the Pasteur Network’s global research community.

Ceremony of the Pasteur Network Annual Meeting, on October 22, 2025, in Ho Chi Minh City (Vietnam), Dr. Grégoire Davignon, molecular biologist at the Institut Pasteur of New Caledonia and associate researcher at the University of New Caledonia, receives the Talent Award. This distinction, funded since 2017 by the Institut Pasteur Paris, highlights young researchers from the Pasteur Network who have demonstrated strong scientific potential. For the second time, the award recognizes excellence in the Science & Communication category, honoring researchers who bridge the gap between research and society.
A scientific commitment to global health
Dr. Grégoire Davignon leads innovative research on leptospirosis, a neglected zoonotic disease with increasing public health relevance, particularly in tropical regions. His work focuses on the gene regulation mechanisms of Leptospira interrogans biofilms, which play a crucial role in the bacterium’s ability to adapt and persist in the environment.
Using New Caledonia—a territory where leptospirosis places a disproportionate burden on vulnerable populations—as a primary study area, Dr. Davignon’s research adopts a One Health approach, exploring the interconnectedness of animal, human, and environmental health. His findings are pivotal for better understanding the risks associated with leptospirosis and for designing prevention strategies tailored to tropical ecosystems.
He has presented his work at prestigious international conferences in Los Angeles, Belgium, and Paris, positioning his research on the global stage and reinforcing the role of the Pasteur Network in addressing re-emerging infectious diseases.
A voice for science, beyond the lab
Beyond his scientific contributions, Dr. Davignon is deeply engaged in science communication and public outreach. As a semi-finalist in the French national competition “Ma Thèse en 180 secondes”, he delivered an accessible and engaging presentation of his research to a broad audience. His communication skills also earned him recognition at an international innovation hackathon in Australia, where he successfully pitched a project on algae-derived biomaterials.
An advocate for making science accessible, Dr. Davignon actively participates in public events such as the Fête de la Science, and he regularly engages with both academic and non-academic audiences. He has represented New Caledonian youth in discussions with Pacific Islands Forum leaders and participated in high-level exchanges with policymakers, including a meeting with the French Overseas Minister.
Supporting the next generation of scientists
In addition to his scientific and communication achievements, Dr. Davignon has demonstrated a strong commitment to education and mentorship. As former President of the Doctoral Students’ Association of New Caledonia, he supported early-career researchers and helped foster a vibrant scientific community.
Empowering science to speak to society
In presenting the award, Odette Tomescu Hatto, Vice President of International Affairs at Institut Pasteur, emphasized: “he Talent Award today celebrates a scientist who embodies not only scientific excellence, but also the ability to translate his research into concrete action, accessible to all. Dr. Grégoire Davignon demonstrates that scientific communication is a powerful tool for shaping the future of public health”
This 9th edition of the Talent Award continues to highlight the vital role of scientific communication in public health. Dr. Davignon’s career is a testament to the synergy between research and outreach—a dual commitment that brings science closer to the people it serves
As part of the 2025 edition of Health: A Political Choice – The Future of Health in a Fractured World (released on October 6th), a flagship publication of the Global Governance Project, co-edited by the Global Health Centre (Geneva) and the Global Governance Program (Toronto), an article (pp. 70–71) is dedicated to “Science and Solidarity: A New Paradigm for Global Health” by Yasmine Belkaid, President of Institut Pasteur and Vice-President of the Pasteur Network, Mario Santos Moreira, President of the Pasteur Network and President Fiocruz, and Rebecca Grais, Executive Director of the Pasteur Network.
In their article, the authors argue that in a world fractured by crises and mistrust, science remains one of the few truly global connective threads. They emphasize that sustained, decentralized scientific collaboration is essential to achieving equity and preparedness in global health. The COVID-19 pandemic revealed both the immense power of scientific cooperation and the deep inequities in access to life-saving tools.
The authors call for a new paradigm—one that moves beyond selective solidarity toward shared responsibility, long-term investment, and inclusive governance. They highlight the Pasteur Network as a model of trust-based, multipolar collaboration that delivers public goods and strengthens resilience across borders.
The Pasteur Network exemplifies this vision. With over 30 member institutions across five continents—most located in the Global South—it fosters decentralized innovation and rapid responses to emerging health threats. During the COVID-19 pandemic, its members exchanged genomic data, protocols, and reagents in real time, often faster than through formal channels. These efforts were grounded in trust, scientific excellence, and long-standing partnerships.
The article concludes with a call to invest in the infrastructure of cooperation: networks, platforms, and inclusive governance mechanisms. The breakthroughs of the future, the authors argue, will not arise from isolated efforts but from organized collaboration grounded in equity and solidarity.
The Pasteur Network announces the launch of PNLink, an exclusive digital platform designed to enhance collaboration, communication, and knowledge sharing among its 32 member institutes worldwide.
PNLink provides members with an intuitive environment for a global interaction and coordination on priority health challenges such as epidemic preparedness, climate-sensitive diseases, vaccine development, and antimicrobial resistance.
This launch reflects the Network’s strategic pillar to foster multidisciplinary collaboration and global knowledge exchange.
“The launch of PNLink is a pivotal step forward in harnessing the power of collective intelligence within the Pasteur Network. This platform embodies our commitment to openness, inclusivity, and scientific excellence, enabling faster and more agile responses to global health threats,” Rebecca F. Grais, Executive Director of the Pasteur Network.
