Stephen George Simpson is an American mathematician whose research concerns mathematical logic, the foundations of mathematics, and Ramsey theory. He is known as one of the founders of the field of reverse mathematics, in which the goal is to determine which axioms are needed to prove certain mathematical theorems.[1] He has also argued against the mathematical existence of actual infinity.[2]

A conference in honor of Simpson's 70th birthday is being organized in May 2016.[3]

Academic biography

Simpson graduated in 1966 from Lehigh University with a B.A. (summa cum laude) and M.A. in mathematics.[4] He earned a Ph.D. from the Massachusetts Institute of Technology in 1971, with a dissertation entitled Admissible Ordinals and Recursion Theory and supervised by Gerald Sacks.[5]

After short-term positions at Yale University, the University of California, Berkeley, and the University of Oxford, he became an assistant professor at the Pennsylvania State University in 1975. At Penn State, he was Raymond N. Shibley professor from 1987 to 1992.[4]

In 2016 his wife, computer scientist Padma Raghavan, moved from Penn State to Vanderbilt University to become vice provost for research,[6] and Simpson followed her, becoming a research professor at Vanderbilt.[7]
