The Cahill group uses advanced imaging techniques, such as high-resolution magic angle spinning magnetic resonance spectroscopy and high-frequency ultrasound, to study experimental mouse models of neurodegenerative, neurodevelopmental and pregnancy disorders. In addition to the study of healthy pregnancies, the Cahill group is interested in the impact of environmental exposures (e.g., micro-/nanoplastics and poly- and perfluoroalkyl substances) on pregnancy outcomes and studies pregnancy complications including fetal growth restriction, preterm birth, and stillbirth. They are also running several human studies focused on testing novel imaging biomarkers for pregnancy complications and investigating the impacts of exposure to micro-/nanoplastics on pregnancy and fetal development.
