Welcome to my home page, last revised October 15, 2015. 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 a grant from 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.

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