Joseph B. Keller, Doctor of Science

A mathematician of broad acclaim and accomplishment, Keller’s research concerns the use of mathematics to solve problems of science and engineering. Among other breakthroughs, he developed the Geometrical Theory of Diffraction to describe the propagation of waves. It is widely used to analyze radar reflection from objects, to calculate elastic wave scattering from flaws in solids, to study acoustic wave propagation in the ocean and for other purposes. He is also known for his formulation of the EBK method of quantization to determine energy levels of atoms and molecules in quantum mechanics and to solve characteristic value problems in other fields. From the 1940s to 1979, he was on faculty at New York University before moving to Stanford, where he continues as Professor Emeritus. Among many other awards, he is the recipient of the Wolf Prize, the Frederick E. Nemmers Prize and the National Medal of Science.
