About the Presenters

Jacquie Bay   |  Deborah Sloboda

Developmental Origins and Epigenetics Research at The Liggins Institute

Dr Deborah Sloboda and Dr Mark Vickers lead the Developmental Origins of Health and Disease (DOHaD) research group at the Liggins Institute. This group is interested in understanding the impact of maternal nutrition on health and wellbeing in offspring. Many members of the Liggins Institute, including Professor Peter Gluckman who leads the Evolutionary Biology and Epigenetics research group are investigating how epigenetic mechanisms underpin the relationship between early life environment and phenotype. Dr Sloboda, Dr Vickers and Professor Gluckman collaborate with scientists from AgResearch, The Singapore Institute of Clinical Sciences (A*STAR), the University of Southampton DOHaD Institute led by Professor Mark Hanson and McGill University Montreal.
