Research Interests

Seed Biology

My research interests are in all aspects of seed biology, from the genetics, molecular biology and physiology of seed development, dormancy and germination to the production, storage, enhancement and utilization of seeds for agricultural purposes. I also am involved in mathematical modeling of seed germination responses to environmental inputs with applications for seed ecology. My disciplinary expertise is primarily in the hormonal regulation of plant growth and development and plant water relations. I am Director of the Seed Biotechnology Center and am engaged in research, extension and public service relevant to the seed and plant biotechnology industries.
