He obtained his Ph.D. at the University of Washington (Seattle) under the supervision of Allendoefer.[2] In 1971 together with Jean Dieudonné he received the Leroy P. Steele Prize for the article Invariant theory, old and new.[3][4]
He proved theorems in Schubert calculus about singularities of Schubert varieties. The Carrell–Liebermann theorem on the zero set of a holomorphic vector field is used in complex algebraic geometry.
He is a fellow of the American Mathematical Society.[5]
