Tadao Oda (小田忠雄, Oda Tadao) (born 1940, Kyoto) is a Japanese mathematician working in the field of algebraic geometry, especially toric varieties.
The field of toric varieties was developed by Demazure, Mumford, Miyake, Oda and others in the 1970s.
[1] In 1958 Oda graduated from Tokai High School in Nagoya, Japan, where Shigefumi Mori and Hisasi Morikawa also graduated from.
He earned his bachelor's degree from Kyoto University in 1962, and five years later earned a Ph.D. under David Mumford from Harvard University with thesis Abelian varieties over a perfect field and Dieudonné Modules.
Oda wrote "Algebraic Geometry, Sendai, 1985" with Hisasi Morikawa, a former professor at Nagoya University.
