Steve Simpson's Home Page

Welcome to my home page, last revised January 7, 2016. Please send your comments to me at

My full name is Stephen G. Simpson. I am a senior mathematician at the Pennsylvania State University. I am active in mathematical research and in the mentoring of undergraduates, Ph.D. students, postdocs, and faculty members in our Department of Mathematics. My principal research areas are mathematical logic and foundations of mathematics.

My research is currently supported by the Simons Foundation. In the recent past my research has been supported by the National Science Foundation, the Templeton Foundation, and Penn State's Eberly College of Science.

Recently I have been cited in the popular science press. See Math in 100 Key Breakthroughs, by Richard Elwes, and an article in Scientific American, by Natalie Wolchover.

In January 2016 I gave a general-audience public lecture on the foundations of mathematics.

In May 2016 there will be a conference in honor of my 70th birthday.

My wife is Padma Raghavan. Here at Penn State, Padma is the Associate Vice President for Research, the Director of the Institute for CyberScience, and a Distinguished Professor of Computer Science and Engineering.

In January 2016 Padma and I will move permanently to Vanderbilt University. Padma will be the Vice Provost for Research and a Professor of Electrical Engineering and Computer Science. I will be a Research Professor of Mathematics.
