Greg Edmeades is a fellow of the Crop Science Society of America. He was raised on a dairy farm in New Zealand, studied agriculture and crop science at Massey University, and completed his Ph.D. in maize physiology at the University of Guelph in Canada. In 1976, he joined CIMMYT Mexico as a postdoctoral researcher. From 1979 to 1984 he managed an on-farm research project in Ghana funded by the former Canadian International Development Agency aimed at increasing maize and cowpea production for smallholder farmers. Edmeades then returned to CIMMYT headquarters in Mexico where he led a physiology program focused on developing maize varieties with tolerance to drought and low soil fertility. In 1999, Edmeades joined Pioneer Hi-Bred International and was based in Hawaii, continuing his work on field aspects of drought and low N tolerance. In 2004, he retired from Pioneer and returned to New Zealand where he consults as a research project reviewer in sub-Saharan Africa and Southeast Asia. He and his wife have two grown sons and two grandchildren.
