Corina Lesseur, MD, PhD, is Assistant Professor in the Department of Environmental Medicine at the Icahn School of Medicine at Mount Sinai.  Dr. Lesseur's research is focused on characterizing the molecular landscape of the human placenta and how it is affected by environmental exposures and pregnancy complications. Her work aims to better understand how the prenatal environment captured in the placenta shapes health outcomes for both mothers and children.

Chelsea DeBolt, MD, MSCR, is a board-certified obstetrician-gynecologist and a maternal-fetal medicine specialist at The Mount Sinai Hospital and an Assistant Professor in the Department of Obstetrics, Gynecology and Reproductive Science at the Icahn School of Medicine at Mount Sinai. Dr. DeBolt’s practice focuses on high-risk pregnancies, with special interest in prenatal diagnosis. Her research is focused on improving women’s health across the lifespan through understanding the biological drivers of optimal and adverse pregnancy health, including preeclampsia, preterm birth, fetal growth restriction, and stillbirth.

Description: In this webinar, Drs. Lesseur and DeBolt will discuss emerging research on chemical exposures and placental health, highlighting how the placenta acts as a critical interface between the mother and the developing fetus. They will explore how exposure to environmental chemicals may influence the placenta, fetal growth, and long-term health, and why the placenta is a key—yet often overlooked—target in environmental health research.

Moderator: Kirstyn Bonetti, Advisory Board Member, Mount Sinai Institute for Exposomic Research

Duration: 25 minute talk + 20 minutes Q&A

This community webinar is part of the Mount Sinai Institute for Exposomic Research Environment and Health Lunchtime Chat Series. Scientists at the Icahn School of Medicine at Mount Sinai are advancing research that reveals how environmental exposures—from air pollution and chemicals to social and lifestyle factors—shape health across the lifespan. Through this webinar series, we translate discovery into action, connecting groundbreaking science to real-world insights that empower families and communities to make informed choices and support long-term health.
