Senior Scientist and Genetic Resource Specialist Fiona Hay

Fiona is a seed physiologist who ensures International Rice Genebank procedures are optimized for effective seed conservation.

Fiona and her research team are looking at seed longevity, development, dormancy, and germination. They also assess regeneration and characterization procedures. Fiona is coordinator for the Global Strategy for the Ex Situ Conservation of Rice. She is also an associate editor of Seed Science & Technology and compiles the biannual newsletter for the International Society for Seed Science.
