Research Interests
Dr. Powell is internationally recognized for her work in determining the molecular mechanisms regulating ion and macronutrient transport in the human placenta and characterizing changes in placental function in association to important pregnancy complications. Currently, the primary focus of Dr. Powell’s research is to better understand how the abnormal metabolic environment of obesity or gestational diabetes in pregnant women affects placental function and the long-term health of her baby. Specifically, Dr. Powell is interested in identifying endocrine signals linking maternal adipose tissue to placental function and fetal growth and developing novel intervention paradigms for improving the maternal metabolic environment and pregnancy outcomes in obese women.
