Dr. Ophelia Yin, an investigator at the March of Dimes Prematurity Research Center at the University of California, San Francisco, on her recent research finding four new genes associated with cellular changes in the uterus during preeclampsia — findings that have helped widen the aperture of preeclampsia research past the placenta and into the uterus.

Dr. Christina Megli, a 2025 March of Dimes Basil O’Connor Starter Scholar Research Award winner, discusses her discovery of 'first responder' macrophage immune cells in the amniotic sac in healthy pregnancy — a finding that may one day lead to new risk prediction tests and therapeutics to slow or prevent preterm birth.

Dr. Brice Gaudillière, an investigator at the March of Dimes Prematurity Research Center at Stanford, on an upcoming Randomized Controlled Trial he is heading that will test two common over the counter drugs — Aspirin and Prevacid, an acid reflux medication — as possible therapeutics to prevent spontaneous preterm birth.

Dr. Frank Lee, a Professor of Pathology and Laboratory Medicine at the University of Pennsylvania Perelman School of Medicine and a 2026 winner of a March of Dimes Discovery Grant, discusses his research on HIF2 gene suppression as a way to treat preeclampsia.

Dr. Brice Gaudillière, an investigator at the March of Dimes Prematurity Research Center at Stanford University, discusses a breakthrough Machine Learning (ML) algorithm that makes reliable predictions about labor onset, preterm birth, and preeclampsia and also identifies the biological markers supporting those predictions.
 

Dr. Marisa Bartolomei, a University of Pennsylvania professor of cell and developmental biology, co-director of the university's Epigenetics Institute, and winner of the 2024 March of Dimes Richard B. Johnston, Jr., MD Prize, on discovering one of the first imprinted genes, making connections between imprinted gene mutations and developmental disorders, and uncovering the exact pathways of gene imprinting defects: namely, abnormalities in DNA methylation.

Former Stanford PRC collaborator Dr. Jonas Miller, now a Psychological Sciences Assistant Professor at the University of Connecticut, discusses how the stress a woman experiences before pregnancy is associated with the way her child's brain functions around three to five years old. Those children, Dr. Miller found, have a harder time with impulse control.

Dr. Tim Hand, a March of Dimes researcher at the University of Pittsburgh, discusses the link between breast milk and a life-threatening preterm birth-related condition called necrotizing enterocolitis (NEC). As it turns out, not all breast milk is protective against NEC.
