Dr. Lumey studied medicine at the Universities of Leiden and Amsterdam in the Netherlands and history and philosophy of science at Darwin College, University of Cambridge, England. He was awarded a Fulbright fellowship to study at Columbia University where he obtained MPH and PhD degrees in epidemiology. After returning to the Netherlands, Dr Lumey worked at the Academic Medical Center of the University of Amsterdam and the National Institute for Public Health and Environmental Protection RIVM. He later joined the American Health Foundation in New York and was Director of the New York City Perinatal HIV Transmission Collaborative Study before being recruited to the Department of Epidemiology at Columbia. Over the last decades, Dr Lumey completed a number of single and multi-generation cohort studies worldwide to investigate the relation between maternal nutrition in pregnancy and health outcomes in the offspring. These studies include men and women exposed to malnutrition during the Ukraine famine of 1932-33, the Dutch famine of 1944-45, and the Chinese famine of 1959-61. He has reported extensively on morbidity and mortality, including birth outcomes, infant growth, and adult health, including epigenetic changes. With collaborators in Leiden, he published in 2008 the first study in humans linking prenatal famine to persisting epigenetic changes in DNA methylation of the IGF2 gene. Further studies in the Dutch famine population show that DNA methylation could be an epigenetic mediator of the impact of prenatal nutrition on adult health.
