Dr. Rachel Yehuda, professor of psychiatry at Icahn School of Medicine at Mount Sinai, has conducted a depth of research into epigenetics and the intergenerational transmission of trauma. In layman's terms, she is researching how serious incidents of trauma (i.e. slavery, holocaust, etc.) and post-traumatic stress disorder (PTSD) can be passed down through generations in shared family genes. Her research has revealed that when people experience trauma, it changes their genes in a very specific and noticeable way, so when those people have children and their genes are passed down to their children, the children also inherit the genes affected by trauma.
