Summary
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.
