I am a seed scientist with interests that span seed physiology, ecology, and technology. My research aims to improve our ability to conserve seeds of wild plant species and to enhance our capacity for ecological restoration.
My research includes studies of seed survival and longevity in conservation seed banks and in the field, the environmental factors that regulate seed dormancy and germination, and the development of seed enhancement techniques to promote seedling establishment.
