Ionescu-Tulcea received his diploma in 1946 at the University of Bucharest , was professor in Bucharest from 1952, was at Yale University from 1957 and received his doctorate in 1959 under Einar Hille in Yale (Semi-Groups of Operators).

In the 1960s, both developed the lifting theory initiated by John von Neumann in functional analysis with applications in probability theory. The Ionescu-Tulcea theorem , an important existence theorem for discrete-time stochastic processes, is named after him (1949). He also dealt with mathematical game theory and mathematical economics. He wrote several textbooks and also books on blackjack .

In 1957 he received the award of the Romanian Academy of Sciences. Robert Langlands is one of his PhD students .
