Research Interests

Physiology, genetics, ecology, biochemistry, molecular biology and biophysics of seed development, dormancy, germination, and longevity; hormonal regulation of seed and plant development; mathematical modeling of germination responses to environmental factors; agricultural biotechnology.

 

Extramural grants and activities

Principal Investigator on extramural grants from the NSF, USDA, USAID and seed industry groups and companies. 

 

Organized the Western Regional Seed Physiology Research Group, a unique voluntary cooperative effort of horticultural seed companies to fund a University-based fundamental research program targeted to the long-term needs of the seed industry. This Group has been in continuous operation since 1989 with an average of 12 member companies.

 

Founding Director of the UC Davis Seed Biotechnology Center (http://sbc.ucdavis.edu), a research, education and outreach unit of the College of Agricultural and Environmental Sciences dedicated to the development and commercialization of new plant and seed technologies for agricultural and consumer benefit. The SBC develops and operates research and education programs including the Plant Breeding AcademySM (http://pba.ucdavis.edu), which offers breeder education programs in the US, Europe, Asia (Thailand) and Africa.

 

Co-founder with Francois Korn (owner of SeedQuest (www.seedquest.com)) of Seed Central (www.seedcentral.org), an organization focusing on energizing the seed industry cluster in California and enhancing technology transfer from UC Davis to applications in plant breeding, seed production, agriculture and food technology.
