Lea Maitre

Assistant Research Professor Exposoma, Malalties no transmissibles i medi ambient

Léa Maitre is an Assistant Research Professor at ISGlobal and coordinates the Exposome
initiative, promoting innovation, collaboration and communication about this new field of
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), and WP leadership in the
International Human Exposome Network project (2024-2026). 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).
