Studying agronomy at McGill University, he earned Bachelor of Science and master of science degrees. He obtained his Ph.D. at Cornell University in 1971 for his work in soil chemistry.[2]

As an agronomist for the International Development Research Centre (Canada), he worked from 1971 to 75 on a project for Cáqueza, Columbia. He worked in the Philippines at the International Rice Research Institute. Thereafter, he went to Lima, Peru as director of the International Potato Center from 1991 to 2005.
