Of special note is his landmark article, A Formal Description of System/360, describing the then new IBM System/360 computer system, formally, in APL programming notation.

Falkoff was a visiting member of the faculty of IBM's Systems Research Institute, and taught Computer Science at Yale University. He was one of the researchers who established and managed the IBM Philadelphia Scientific Center and received numerous awards for his work, especially for his work with APL.
