Research Interests
My research focuses on the regulation of vascular function during pregnancy and how it impacts fetal growth. I am currently investigating how potassium channels, which are known regulators of vascular reactivity, modulate uterine vasodilation and the maternal cardiovascular adaptation to pregnancy and how the activity of these channels is impaired in pregnancy complications such as intrauterine growth restriction.
