Emeritus Professor, School of Integrative Plant Science Plant Breeding and Genetics Section
I lead the Cornell Forage Breeding Project to conduct genetic research and develop cool season, perennial forage cultivars with higher yield, multiple disease and insect resistances, and forage quality. My project conducts research on use of perennial grasses and legumes as feedstocks for the biofuel industry. I also do research on performance and breeding of industrial hemp cultivars. I teach plant breeding and quantitative genetics; and my project provides extension and outreach information to seed companies, other breeders, extension educators, and producers. As associate dean and director of academic programs, I also provide oversight to the improvement of academic programs in the college.
Forage breeding and genomics
My research objectives are to breed improved forage cultivars (primarily alfalfa and birdsfoot trefoil) for Northeast USA and promote their use by growers and seed companies. Although private breeding companies now provide most of the alfalfa cultivars in the USA, none of them focuses on traits specifically needed in the Northeast. Because there are few forage breeders in North America, a large proportion of my research is cooperative, facilitated through the NE1710 Multistate Cooperative Research Project. This project includes research to improve forage species, compare breeding methods, evaluate new cultivars of several forage species for yield, and conduct QTL and other genomic analyses. I am cooperating with other scientists in NE1710 to identify QTLs for forage yield and other agronomic traits. In 2005, I began efforts to evaluate perennial, warm season grasses (especially switchgrass) and breed them for use as feedstocks for biofuels. In 2016, my project began breeding research on industrial hemp.

My professional objectives include preparing students for plant science careers through my advising and teaching. My quantitative genetics course is structured for students to learn practical methods of quantitative genetic experimentation and to understand how plant breeders can maximize progress from selection for quantitative traits. Administratively, I enjoy facilitating the creation and implementation of academic programs and policies in CALS and across the University. I also enjoy organizing faculty development workshops in teaching.
Until 2016, I have taught PLBRG 7170, Quantitative Genetics in Plant Breeding, in alternate years. I annually teach three 75-minute class periods of PLBRG 4030, Genetic Improvement of Crop Plants, and one afternoon field lab on forage breeding in PLBRG 4060, Methods of Plant Breeding Laboratory.

Contrary to popular belief, new research shows that a hemp plant’s propensity to become too high in THC is determined by genetics and not as a stress response to growing conditions.
