1960) and Harvard University (master's degree 1961), where he graduated in 1965 after studying under Raoul Bott (Künneth formulas for bordism theories).
In the beginning of the 1970s, he proved his exact functor theorem, which allows the construction of a homology theory from a formal group law.
[5] In 1986 he introduced elliptic cohomology with Douglas C. Ravenel and Robert E. Stong, which is a generalized cohomology theory with applications to modular forms and elliptic curves.
[6] From 1989 to 1992 he was Chairman of the Russian translation Committee of the American Mathematical Society.
