Project EDC-MixRisk: In focus – Dr. Barbara Demeneix

EDC-Mix risk

Meet our EDC-MixRisk scientists and learn more about the work they are doing. This time in the spotlight is Barbara Demeneix, Professor at the French National Museum of Natural History. She is an internationally recognized expert on thyroid function and endocrine disruption. In the EDC-MixRisk project, her group studies how chemical mixtures affect thyroid hormone signalling. 

Hi Barbara – What are you and your research group studying in the project?

We are using an amphibian embryo to study how the different chemical mixtures affect thyroid hormone signalling. We have known for decades that thyroid hormone is essential for brain development in all vertebrates. This is why all babies born today are tested in the first few days after birth to check that they have sufficiently thyroid hormone to ensure proper brain development. More recently, we have learned from epidemiological studies that during pregnancy, especially the first few months, a mother’s thyroid hormone levels are associated with the developing child’s IQ and even the structure of their brain.
