My research interests encompass the cellular and molecular mechanisms of placental development and function. There are two reasons I am interested in studying the placenta. First, the placenta is an exceptionally unique organ, one with evolutionary adaptations not observed in any other tissue. The second reason is from a public health perspective. The placenta intimately connects a mother with her developing baby, and it performs vital functions required for pregnancy such as regulating nutrient exchange between maternal and fetal blood, and producing hormones necessary for fetal development. Placental maldevelopment or dysfunction is linked with a variety of pregnancy complications (e.g. pre-eclampsia, fetal growth restriction, pre-term birth, placenta accreta, spontaneous abortion) that cause significant maternal and fetal illness or death. Despite its importance for the health of mothers and their babies, we really don’t have a good grasp on how the placenta develops or functions.
Our research interests can be broadly divided into two themes:
