“Joana Palha is full professor of biochemistry at the School of Medicine, University of Minho (Braga, Portugal). PhD in Biomedical Sciences in 1995 (University of Porto, Portugal, research project at Columbia University, New York, USA), MSc in Public Health in 2016 (Karolinska Institute, Stockholm, Sweden), BSc in Biochemistry (University of Porto, Portugal). Published over 100 articles in peer-reviewed journals. Principal investigator of several research projects has supervised 15 PhD students (14 completed). Serves/has served in several national and international organizations (National Council for Science, Technology and Innovation, International Brain Research Organization, COST, Society for Neurosciences USA, Portuguese Society for Neurosciences, Portuguese Foundation for Science and Technology, BIAL Foundation), evaluates for several journals and funding agencies (European Commission, Disease Foundations, European Agencies), and is regularly member of scientific committees/chair of conferences/congresses. She started her career in 1992 on thyroid hormones, studying one of the first knock-out mouse models. She led pioneer studies that revealed an endocrine function of the blood brain barriers, particularly the choroid plexus, in brain homeostasis. She has been coordinating translational and clinical research, with focus on the endocrine axis. Her studies in humans have recently contributed to the change in the national policy on iodine supplementation to the Portuguese population, with specific guidelines for women in reproductive age and pregnant women.

Iodine and maternal and child’s health

Iodine deficiency is the most common cause of PREVENTABLE brain damage in infants, impairing the achievement of their full intellectual capabilities. Iodine is needed for the synthesis of thyroid hormones (TH)…
