Dennis Gonsalves

Gonsalves was born and raised on a sugar plantation in Kohala, Hawaii. He studied horticulture (BS, 1965) and phytopathology at the University of Hawaii. His doctorate was in 1968 at the University of California, Davis. From 1972 to 1977 he worked at the University of Florida and from 1977 to 2002 at Cornell University, where he became a professor in 1995. Since 2002 he was the director of a USDA research center in Hilo and is now retired and living in Hawaii. == Work ==

Gonsalves began his research career at Cornell University working on virus-resistant plants. While on a trip back home to Hawaii, he learned from local farmers that a virus was rapidly making its way toward the Big Island's Puna District, where the majority of the state's papayas were grown. This led to his starting a research program in 1985 that resulted in the creation of a papaya with resistance to the papaya ringspot virus. His work is recognized worldwide and has received several awards. His Rainbow papaya makes up about 77 percent of the Hawaii's crop. == Awards ==
