Léa Maitre is an Assistant Research Professor at ISGlobal and coordinates the Exposome Hub, promoting innovation, collaboration and communication about this new field of
research.
During her Ph.D. and first postdoc position at Imperial College London, United Kingdom, she obtained extensive experience on metabolomics and pregnancy outcomes, acquiring broad knowledge in NMR spectroscopy and advanced statistical methods in molecular epidemiology. Since then, she has focused on the extension of this field in the Exposome.

Her participation in European projects on this topic included the scientific coordination in the HELIX project (2013-2018), task leadership in the ATHLETE project (2020-2024), WP leadership in the International Human Exposome Network project (2024-2026) and in ENDOMIX (2024-2028). She has been teaching and coordinating a 5- days online course on Exposome advanced tools as part of the International
Summer School on Advanced Methods in Global Health in English and Spanish.

Her main research interests are in the application of interdisciplinary research (omics, environmental epidemiology, toxicology) to understand early life environmental influences on
health and biological mechanisms. She received the Ramon y Cajal fellowship by the Spanish Government (2024-2029).
