Summary

David Balshaw, Director of Extramural Research at NIEHS, delivers a keynote address at the Global Exposomics for Brain Health Symposium 2026. He traces the history of the exposome concept from its roots in the Human Genome Project and the 2005 paper by Chris Wild, through the development of exposure assessment technologies and NIH initiatives like the Genes, Environment, and Health Initiative. He highlights key milestones such as the 2010 Science paper by Rappaport and Smith, and the first NHANES-based exposome study by Patel et al. Balshaw discusses the growth of the field, with nearly 1000 exposome publications expected in 2026, and emphasizes the need for global coordination to launch a Human Exposome Project. He outlines future directions including precision environmental health, integration with other omics, and the commoditization of exposomic analysis. He also addresses challenges such as defining the scope of the exposome and the need for longitudinal studies. The talk concludes with a Q&A session where he discusses the dynamic nature of the exposome and the potential for using cross-sectional studies to approximate life-course exposure.

Critical Evaluation

Value of the Information & Strength of the Argument

The talk provides valuable historical context and insights into the development of the exposome field, drawing on the speaker’s direct involvement in NIH programs. The argumentation is coherent and well-structured, tracing the evolution from early exposure assessment to current global initiatives. Balshaw effectively argues for the importance of the exposome in understanding disease etiology and the need for a global Human Exposome Project. He supports his points with references to key publications and programs, though some claims could benefit from more specific citations. The discussion of future directions is thought-provoking, particularly the emphasis on precision environmental health and the commoditization of exposomic technologies.
