Calabi was a Putnam Fellow as an undergraduate at MIT in 1946. In 1950 he received his Ph.D. from Princeton University, where his advisor was Salomon Bochner.[2] He later obtained a professorship at the University of Minnesota.

In 1964, Calabi joined the mathematics faculty at the University of Pennsylvania. Following the retirement of the German-born American mathematician Hans Rademacher, he was appointed to the Thomas A. Scott Professorship of Mathematics at the University of Pennsylvania in 1967. He won the Steele Prize from the American Mathematical Society in 1991 for his work in differential geometry. In 1994, Calabi assumed emeritus status. In 2012 he became a fellow of the American Mathematical Society.[3]

His work on the Calabi conjecture for Kähler metrics led to the development of Calabi–Yau manifolds, and the study of constant scalar curvature Kähler metric and extremal Kähler metric introduced by him in 1982 is a central topic in complex differential geometry.
