Year Appointed: 2000
Rank: Professor and Endowed Chair Corn Breeding and Genetics
Areas of Interest
Maize breeding and statistical genetics

Research
I discover new ways of breeding corn, breed corn for new uses, and educate future plant breeders. My interests include exploiting new technologies in applied corn breeding and elucidating the nature of genetic variation for quantitative traits.
