Human Exposome Project: Unlocking Health & Future of Medicine | AAAS 2026

A groundbreaking international initiative to map the totality of human exposure to environmental factors – the human exposome – is gaining momentum, with significant progress updates scheduled to be presented at the February 14th, 2026, meeting of the American Association for the Advancement of Science (AAAS) in Phoenix, Arizona.

A session moderated by the Financial Times, titled “How the human exposome will unlock better health and medicine,” will feature leaders from the Global Exposome Forum, outlining advancements made since the project’s launch in Washington D.C. In May 2025. The discussion aims to introduce the potential of exposomics research to a broad scientific audience.

The human exposome encompasses the lifetime accumulation of exposures from the environment – everything from diet and lifestyle to pollutants and social interactions – and how these factors interact with our genes to influence health. While the Human Genome Project revolutionized our understanding of genetic predisposition to disease, it’s estimated that genetics account for only 10-20% of disease risk. The remaining 80% or more is believed to be attributable to environmental exposures.

“We are here to make waves, not ripples,” stated Prof. Thomas Hartung of Johns Hopkins University Bloomberg School of Public Health, organizer of the AAAS panel. “Our Committee Members have been putting in the hard yards over these past nine-months and the surge in interest leading to concrete set-up events and firm commitments is tremendous to see. We have much positive news in the pipeline and during our panel discussion we’ll announce three examples representing buy-in with national governments, global scientific institutions and large membership-led organizations.”

Understanding the Exposome: A Paradigm Shift in Public Health

The Global Exposome Forum is fostering a collaborative, international approach to studying the exposome, recognizing the need for large-scale, coordinated efforts. Panelists will focus on three key areas: the potential of exposomics research, a strategic plan for building a global network, and strategies for overcoming scientific and policy challenges. This includes leveraging advancements in artificial intelligence, sensor technology, metabolomics, and big data analytics to analyze the complex interplay of exposures and health outcomes.

The initiative is designed to move beyond simply identifying individual risk factors and towards understanding how combinations of exposures impact health. This holistic approach is crucial, as individuals are rarely exposed to single agents in isolation. Researchers are increasingly focused on translating these scientific discoveries into policies that benefit broad populations, rather than focusing on select groups.

Pan-African Collaboration and Global Expansion

The project is rapidly expanding geographically. In December 2025, the South African government, through its Science Forum South Africa and the World Conference of Science Journalists, convened national and pan-African experts to explore the feasibility of creating a continent-wide exposome network. This followed South Africa’s participation in the Washington D.C. Launch of the Human Exposome Project. An agreement was reached for pan-African experts to actively engage with Global Exposome Forum working groups and participate in thematic meetings worldwide, with a focus on improving health data reporting systems.

Regional chapters are also being established in Latin America and the Caribbean, and Southeast Asia, demonstrating the global appeal and relevance of the exposome concept. The European Exposome Forum is organizing the Global Exposome Summit in Sitges, Spain, from April 27th to April 29th, 2026, with registration numbers already exceeding expectations.

Science Advice and Policy Integration

Recognizing that scientific findings must inform policy decisions, the Global Exposome Forum is actively collaborating with organizations like the International Network for Governmental Science Advice (INGSA). INGSA has facilitated discussions on “exposomethics” – the ethical considerations surrounding exposomics research and its application to policymaking – and will continue to advise on strategic engagement with science advisory systems worldwide. A high-level session is scheduled for April 29th, 2026, at the Global Exposome Summit in Sitges, Spain.

A partnership with the Human Cell Atlas (HCA) and UNESCO further underscores the commitment to interdisciplinary collaboration. This collaboration will involve a series of virtual town halls covering single-cell analysis, genomics, exposomics, and science policy. UNESCO is expected to host a follow-up session in Paris on March 3rd, 2026, to prepare for a Memorandum of Understanding between UNESCO and the Global Exposome Forum.

A Grassroots, Collaborative Approach

Central to the Forum’s strategy is the creation of exposome-focused working groups, comprised of participants from industry, government, academia, and civil society. These member-driven teams are tasked with addressing key scientific and policy questions, collaborating through a dedicated digital platform for messaging, document sharing, and coordinated international work. This bottom-up model, engaging both citizens and elected officials, is considered essential for long-term success.

The event at the AAAS Annual Meeting, taking place in room West 105 of the Phoenix Convention Center from 10:00 AM to 11:00 AM MST on Saturday, February 14th, 2026, is open to credentialed members of the press. It offers an opportunity to hear directly from leaders in this rapidly advancing field and learn about a potentially transformative approach to public health and medicine.
