Pamela Ronald is one of the world’s leading scientists on plant genetics, a professor of plant pathology at the University of California, Davis, and the co-author (with her husband, Raoul Adamchuk) of Tomorrow’s Table: Organic Farming, Genetics, and the Future of Food. In this episode, she and Robert talk about the evolution of pathogens, why nearly everything we eat has been genetically modified, her work on developing flood-resistant strains of rice, CRISPR, and why geneticist Barbara McClintock, the winner of the 1983 Nobel Prize in Physiology or Medicine, is one of her personal heroes.
