Rana Dajani studies epigenetics of trauma in vulnerable communities around the world. A molecular biologist based at the Hashemite University in Zarqa, Jordan, her research explores what genes are turned on and off through trauma and if they are transferred to future generations.

In the second episode of an eight-part podcast series to accompany Nature's Changemakers in science Q&A series, collection, Dajani, a daughter of refugees, talks about some formative influences and how she now collaborates with Jordan’s Circassian and Chechen populations, who were violently evicted from their homelands almost two hundred years ago. “I had a treasure trove in my backyard to discover novel gene risk factors for disease that nobody else had discovered, because of their very unique gene pool,” she says.

Changemakers launched last year as a follow-up to the journal's Racism in Science special issue.

Listen to launch editor Kendall Powell discuss the series' aims and objectives with Deborah Daley, global chair of Springer Nature's Black Employee Network.
