We seek to understand the early phases of human development: how the fetus grows, matures, and interacts with its lifeline - the placenta and maternal environment. These formative steps during the 9 months of pregnancy set the stage for 90+ years of health, wellness, and therefore, the future of humankind.

Research in Brief
The placenta at the feto-maternal interface fulfills functions that are critical for intrauterine development, including gas exchange, supply of nutrients, removal of waste products, endocrine regulation, and immunological and physical defense. Our lab utilizes molecular and cellular approaches to decipher mechanisms underlying placental development, differentiation of placental (trophoblast) cells, and their response to injury. We focus on three major areas:
- Placental non-coding RNAs: We use diverse technologies to define the function and regulation of trophoblastic microRNA and long non-coding RNA in response to injuries, such as hypoxia and viral infections.
- Extracellular vesicles at the maternal-placental-fetal interface: We interrogate the mechanisms of release, uptake and function of placental exosomes and other extracellular vesicles.
- Placental lipidomics: We focus on fat trafficking in the feto-placental unit, including the dynamics of lipid droplets and trophoblastic mobilization of fatty acids. We also investigate the function of oxidized phospholipids, which may lead to trophoblast injury, including ferroptotic death.
Using cultured primary human placental cells, genetically-altered mice, and placental samples from normal or pathological human pregnancies, we examine molecular mechanisms underlying trophoblast response to diverse stressors that adversely influence the homeostatic balance between cell injury and adaptation. These stressors contribute to placental dysfunction that underlies diseases such as fetal growth restriction, which predispose to childhood neurodevelopmental dysfunction and adult metabolic syndrome.
