Michigan Center on Lifestage Environmental Exposures and Disease (M-LEEaD) is a National Institute of Environmental Health Sciences Core Center. M-LEEaD improves our understanding of the contribution of environmental exposures toward the etiology of chronic diseases and conditions like asthma, neurodegenerative diseases, metabolic syndrome and prematurity. The M-LEEaD Center supports research in environmental health sciences with three Facility Cores: Integrated Health Sciences Core (IHSC), Exposure Assessment Core (EAC) and Omics and Bioinformatics Core (OBIC).
