Phillip Griffiths

Phillip Augustus Griffiths IV is an American mathematician known for his work in geometry, in particular the complex manifold approach to algebraic geometry. He is a major developer of the theory of variation of Hodge structure in Hodge theory and moduli theory, and he also worked on partial differential equations, coauthoring with Shiing-Shen Chern, Robert Bryant and Robert Gardner on exterior differential systems. He took his PhD at Princeton University in 1962, was a professor at Harvard University from 1972 to 1983, provost and professor at Duke University from 1983 to 1991, and director of the Institute for Advanced Study from 1991 to 2003.
