After postdoctoral fellowships in developmental psychology and in environmental health, Dr. Muckle was professor at the Department of Social and Preventive Medicine at UL for five years before being hired at the School of Psychology in 2003. Her area of specialization, developmental and behavioral teratology, integrates concepts from child development, toxicology and epidemiology. Her research focus on developmental effects of pre- and postnatal exposure to environmental contaminants such as pesticides and heavy metals. This work brought her to work with highly exposed populations like the Inuit of northern Canada. Her work based on a cohort of Inuit children followed from pregnancy to adolescence helped shed light on the developmental effects of mercury, lead and PCB exposure. Dr. Muckle is also co-principal investigator of the Canadian MIREC mother-child cohort providing data on effects of low exposure to environmental chemicals. Results of her work and are used by Canada to support the signing of the Minamata Convention on mercury.
