GermiNation

As she prepares to retire, Susana Goggi reflects on a remarkable career shaping the science—and the people—behind seed technology. In this episode of GermiNation, Dr. Goggi shares how she found her way into seed physiology, the evolution of the field, and why seed scientists are more critical than ever in the face of climate change and global food security challenges. From ensuring seed quality to understanding the full journey from breeder to farmer, she explains why seed science remains the foundation of agriculture—even in an era of AI and biotech. The conversation also highlights a pressing concern: while more students are entering the industry, fewer are pursuing careers in academia—creating a growing gap in training the next generation of seed experts. Plus, hear directly from Iowa State students as they share what excites them about the seed industry, what they’re looking for in their careers, and why mentorship and purpose matter more than salary. This episode is a powerful reminder that behind every harvest is a seed—and behind every seed is a scientist.

What does it really take to become a Registered Seed Technologist (RST), and why does the credential matter more than ever? In this episode of GermiNation, we sit down with two leaders who know the RST journey inside and out: Jessica Blake, Seed Quality Labs Manager at the Iowa State University Seed Science Center, and Quinn Gillespie, President of the Society of Commercial Seed Technologists. Together, they break down the path to becoming an RST, from early training and hands-on experience to preparing for certification exams, and share practical advice for technicians just starting out. They also discuss how foundational skills in seed purity and germination testing build confidence, open doors across the seed industry, and support a career rooted in quality, accuracy, and trust. Whether you’re new to seed testing, considering certification, or mentoring the next generation of seed professionals, this conversation offers insight, encouragement, and a clear roadmap for growing your career in seed science. Because every great seed analyst starts somewhere, and the path matters.

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. Music courtesy of Let’s Roll Snowball. Find them on YouTube.
