Dr. Jacquetta Trasler is internationally recognized for her research in the field of reproductive and developmental epigenomics and its impact on the normal development of children. Her epigenetic studies stand out in considering sex-specific effects along with the impact of both fathers’ and mothers’ exposures to environmental stressors in predisposing their children to adverse health outcomes. Her fundamental studies identified sex-specific windows of epigenetic susceptibility and mechanistic insights into epigenetic inheritance. Her translational studies on the adverse epigenetic and child health consequences of assisted reproduction implicated paternal infertility, sex and individual techniques and identified a role of folic acid in prevention.
