Did you know the toxins and trauma that affected your great grandparents could be influencing how your genes are expressed? Tahira Hayes talks with Dr. Michael Skinner, founding director at the Center for Reproductive Biology at the School of Biological Sciences at Washington State University to explore the groundbreaking topic of epigenetics, the study of heritable changes in gene expression.

Dr. Michael Skinner, is an Oregon native and an Eastlick Distinguished Professor. His research focuses on epigenetics and  transgenerational inheritance of disease phenotypes. His research has been highlighted in BBC, PBS and Smithsonian documentaries and selected as one of the top 100 discoveries in 2005 and 2007 by Discover.
