The science behind safer pregnancies and healthier lives.

The research program of Ravi Goyal, MD, PhD, MBA, FAHA investigates how prenatal and early-life exposures program maternal and offspring cardiovascular disease — using molecular epigenetics, vascular physiology, and computational modeling to identify mechanisms that can be modified before symptoms appear.

Research program

The laboratory's central question.

How do environmental exposures during fetal and early-postnatal life — hypoxia, undernutrition, environmental toxicants, maternal stress — reshape the developing cardiovascular system, and how do those changes lie dormant for decades before manifesting as adult disease?

The Goyal Laboratory approaches this question at three levels. At the molecular level, we map the epigenetic modifications — DNA methylation, histone marks, non-coding RNAs — that translate transient exposures into persistent transcriptional programs. At the tissue level, we characterize the resulting changes in vascular reactivity, contractile protein expression, and endothelial function across the maternal and fetal circulations. At the systems level, we use computational physiology and digital-twin modeling to predict how molecular-level perturbations cascade into clinically observable phenotypes.

This integrated approach is designed to identify intervention windows — moments in development when a modifiable exposure could redirect disease trajectory. The end goal is translational: tools clinicians can use to screen, stratify, and intervene before silent biology becomes overt disease.

Theme 1

Developmental programming of vascular disease

How prenatal hypoxia, undernutrition, and environmental exposures reprogram vascular smooth muscle and endothelial function — driving lifelong hypertension and preeclampsia risk in subsequent generations.

Theme 2

Epigenetic mechanisms

DNA methylation, histone modifications, and non-coding RNA networks that translate early exposures into persistent transcriptional reprogramming — including identification of intervention points.

Theme 3

Maternal-fetal vascular adaptation

How the maternal cardiovascular system adapts to pregnancy, and how prior adverse exposures disrupt that adaptation — relevant to preeclampsia, IUGR, and recurrent pregnancy loss.

Theme 4

Computational and translational physiology

Multiscale modeling, digital twins, and clinical decision-support tools that translate bench observations into bedside applications — exemplified by the PPHrisk and EndoTwin-W platforms.

Developmental programming of maternal vascular dysfunction

Investigates how prenatal environmental exposures alter the maternal vasculature and contribute to hypertensive disorders in subsequent pregnancies. Uses ovine and rodent models, ex vivo vessel physiology, and methylome profiling to identify mechanisms linking exposure history to gestational outcomes.
