Epigenomic studies among infants born preterm: Our studies of infants that were born preterm have examined whether neonatal morbidities and neurobehavioral responses, both of which are associated with later neurobehavioral impairments, are associated with DNA methylation. We have found that many CpG sites throughout the genome are associated with these neonatal factors. Our ongoing and future work aims to test whether these difference in DNA methylation persist with aging and development, how postnatal factors may influence changes in their trajectories, and whether they are predictive of impairments later in childhood.
Studies of Prenatal Environmental Exposures: Much of our research into the impacts of prenatal environmental exposures has focused on how cadmium perturbs gene-expression, regulatory RNAs, and DNA methylation in human placenta. We have shown that genes involved in inflammatory response, growth regulation and neurogenesis are particularly responsive to this prenatal exposure. In addition to cadmium, we have studied the impacts of other metals (arsenic, selenium, copper), maternal tobacco use, and other maternal stressors on genomic regulation.
