JoAnn Trejo co-leads the Faculty Mentor Training Program at the University of California, San Diego (UCSD) medical school, where, thanks to her efforts, the number of tenure-track faculty members from under-represented groups shot up by 38% from 2017 to 2022.

Trejo, a pharmacologist whose research helps to develop drugs to treat vascular diseases, says her mentor colleagues understand that their mission and responsibility is training the next generation of scientists and providing opportunities for them. She describes the people who supported her at the early career stage, and the impact they had. “When I reflect on my life and I think about how a poor Mexican American farm worker kid from an impoverished background became a scientist professor, it’s actually extraordinary,” she says.

Trejo is the seventh researcher to feature in this eight-part Changemakers podcast series. It accompanies an ongoing Nature Q&A series that highlights scientists who fight racism in science and champion inclusion at work.

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