Welcome to my home page, last revised March 14, 2014. 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 research areas are mathematical logic and foundations of mathematics.

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

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 Professor Padma Raghavan, director of the Institute for CyberScience and Associate Vice President for Research here at Penn State.
