Rosalind M John is Professor of Developmental Epigenetics and Director of Research for the School of Biosciences at Cardiff University. With over 20 years of experience, she leads a research group focused on understanding how epigenetic marks direct mammalian development, particularly in utero processes, and how exposure during critical developmental windows can alter outcomes for both mother and child. Her work bridges basic science with clinical applications through the Grown in Wales cohort studies.
Professor John received her PhD from Imperial College, University of London and completed training at University of San Francisco California (UCSF), Stanford, and Cambridge University. Her educational background in genetics and developmental biology has provided the foundation for her pioneering work in genomic imprinting and placental biology.
Her research interests center on genomic imprinting as an epigenetic system that directs allele-specific expression of developmentally important genes. She investigates how imprinted genes regulate fetal growth, placental development, metabolism, and behavior, with particular focus on how environmental factors can influence imprinted gene expression leading to pregnancy complications, mood disorders, and behavioral outcomes. Her laboratory has demonstrated that specific imprinted genes regulate the endocrine compartment of the placenta, thereby modulating placental hormone production that affects both fetal development and maternal adaptations to pregnancy.
Analysis of her recent publications reveals a consistent trajectory of research connecting placental endocrine function with neurobehavioral outcomes. Her work spans from fundamental molecular mechanisms of genomic imprinting to human cohort studies examining how prenatal adversity impacts child development. A key theme is the discovery that offspring can influence maternal behavior before birth through placental imprinted genes, challenging traditional views of maternal-fetal interactions.
- Principal Investigator for the Grown in Wales Study and Grown in Wales Infant Study
- Active supervisor for PhD students in developmental epigenetics
- Recipient of major research funding from MRC, BBSRC, Wellcome Trust, and others
Professor John's research group maintains strong translational connections, working with both experimental murine models and human pregnancy cohorts. They investigate causal relationships through animal models while validating findings in human populations through the Grown in Wales studies. Her team's work has significant implications for understanding and potentially intervening in pregnancy complications, maternal mental health disorders, and neurodevelopmental conditions in children.
