On this episode of GermiNation, we’re joined by a scientist working at the forefront of molecular seed diagnostics: Jeffrey Williams, research scientist at Iowa State University’s Seed Science Center.

Jeffrey’s background spans deep expertise in microbiology and hands-on experience in plant diagnostics, sharpened during his years at Corteva’s Plant Diagnostic Clinic. Now at the Seed Science Center, he plays a critical role in advancing molecular seed quality testing—especially in support of the USDA National Seed Health System, which ensures U.S. seed exports meet strict international phytosanitary standards.

His work fuels global seed trade, strengthens agricultural sustainability, and reinforces the trust farmers place in the seed they plant.

In this episode, we explore Jeffrey’s career path, the molecular puzzles behind seed health, and the curiosity and commitment that drive his research every day.

In this episode of GermiNation, We explore the seeds that connect us - we’re taking you to the Seed Savers Exchange annual conference and 50th anniversary celebration for conversations with leaders working to preserve and protect seed diversity:

We talk to Bonnetta Adeeb – Founding member of Ujamaa Cooperative Farming Alliance and Ujamaa Seeds, on the importance of African Indigenous seeds. www.ujammaseeds.com

Followed by Nicolas Enjalbert – CEO of SeedLinked, discussing groundbreaking research with USDA NIFA, Seed Savers Exchange, and thousands of farmers. www.seedlinked.com

We finish the show with Linda Black Elk, an American Indigenous seed expert, sharing stories and wisdom about traditional foodways. www.natifs.org

From ancestral knowledge to cutting-edge science, this episode celebrates the seeds that connect us all.

In this episode of GermiNation, we take you inside the 2025 World Food Prize Borlaug Dialogue — where innovation, legacy, and global collaboration take center stage. I sit down with three inspiring voices in agriculture: Dr. Manjit Misra, former Director of the ISU Seed Science Center and USDA’s National Institute of Food and Agriculture; Julie Borlaug, President of the Borlaug Foundation, granddaughter of Nobel Laureate Dr. Norman Borlaug and passionate proponent of initiatives to end hunger; and we’ll wrap up with Dr. Jean Baptiste Tignegre, Regional Seed Systems Lead for the African Agricultural Technology Foundation.

Together, they share insights on the past, the present, and the future of feeding the world: from the Green Revolution to the next generation of “Hunger Fighters."

Dr. Vivian Bernau is a plant scientist, educator, and seed advocate whose work bridges the worlds of academic research and hands-on ecological stewardship. From prairie restoration to empowering communities through seed knowledge, she brings a unique perspective to how we grow, preserve, and connect with plants. Whether you’re a gardener, a grower, or just curious about what lies beneath the surface, you’ll love this conversation. So let’s dig in with Dr. Vivian Bernau!

Today, we’re joined by Dr. Scott Heuchelin, the new director of Iowa State University’s Seed Science Center. An ISU alum with over 20 years of experience in seed health and global regulatory policy, Dr. Heuchelin returns to campus after leading international phytosanitary efforts at Corteva Agriscience. Now, he’s guiding the Center into its next chapter of innovation and global agricultural impact.
