Crossing the Atlantic on the Queen Elizabeth ocean liner, Swaminathan worked from 1952 to 1954 at a new Inter-Regional Potato Introduction Station in Sturgeon Bay, Wisconsin, sponsored by the University of Wisconsin and the U.S. Department of Agriculture.
During this period Swaminathan gained practical knowledge of plant hybridization : combining different varieties of the same plant species in order to create a new plant better adapted to the soil and climate conditions of a particular region.
He published nine papers about his experiments, beginning a publishing history that would grow to include an eventual 250 papers and several books.
Offered a professorship at the University of Wisconsin after his stint in Sturgeon Bay, Swaminathan instead chose to return to India instead and work toward making that country a better place to live.
