Epigenetics, which are chemical modifications to the genome that alter gene expression without changing the genetic sequence, are sensitive to environmental exposures and may represent a mechanism for the embodiment of adversity, such as trauma and stress. Additionally, epigenetic changes, may be the link between exposure to trauma and mental health disorders. This talk will discuss her previous research on epigenetics in people living with HIV, as well as her current work with a population of people who use drugs in Nebraska.
