In this half day Masterclass, delivered over 3 hours, Dr Yehuda will explore how molecular biology, genomics, and epigenomics, provide paradigms for understanding the long-term effects of stress. Dr Yehuda will incorporate decades of research on trauma and its impacts, incorporating Vietnam veterans, adult children of holocaust survivors, children of other traumas, children born to pregnant women who survived the 9/11 world trade centre attacks predictors of PTSD to show how early environmental experiences-including parenting- contribute to highly conserved molecular and genomic processes. The masterclass will also present Dr Yehuda’s work and research exploring effective treatments supporting healing and recovery.
