Dr. Maria Jose Talayero Schettino is a postdoctoral researcher at the George Washington University Milken Institute School of Public Health, Department of Global Health. She holds a medical degree, a master’s degree in toxicology, and a Doctorate in Public Health in Environmental and Occupational Health. Her research focuses on environmental health, with an emphasis on chemical exposures, environmental justice, and child health in Latin America and the Caribbean. She is currently collaborating with NIST on the Hurricane Maria Mortality Project and supporting regulatory efforts in public health. 

Dr. Talayero Schettino has a strong background in teaching, policy development, and community engagement. She has worked with UNEP’s Chemicals and Pollution Program, coordinating the Intergovernmental Network on Chemicals and Waste for Latin America and the Caribbean, and volunteers with Mundo Químico, promoting environmental health initiatives. Born and raised in Mexico, she has worked extensively on addressing lead exposure, a pervasive issue culturally embedded in the use of glazed clay pottery. Her work has explored the intersection of lead exposure and criminal behavior, shedding light on its broader societal impacts and advocating for stronger preventive measures. Her efforts aim to protect vulnerable populations while promoting culturally sensitive solutions to reduce lead exposure.

My research centers on global environmental health, with a particular emphasis on the impact of environmental exposures on vulnerable populations in low- and middle-income countries (LMICs). I focus on the intersection of environmental justice and public health, exploring how factors such as lead exposure and pollution contribute to health disparities, especially in Mexico and Latin America. My work spans a range of topics, from birth defects linked to environmental contaminants to the broader implications of industrial pollution on community health.
