Welcome to my home page, last updated November 29, 2016. Please send your comments to me at sgslogic@gmail.com.

My full name is Stephen G. Simpson. I am a senior mathematician at the Pennsylvania State University and at Vanderbilt University. I am active in mathematical research and in the mentoring of undergraduates, Ph.D. students, postdocs, and faculty members. My principal research areas are mathematical logic and foundations of mathematics.  In the recent past my research has been supported by the National Science Foundation, the Templeton Foundation, Penn State’s Eberly College of Science, and the Simons Foundation.

Recently I have been cited and quoted in the popular science press:

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

My wife is Padma Raghavan.  At Penn State, Padma was 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 moved to Vanderbilt University, where Padma is the Vice Provost for Research and I am a Research Professor of Mathematics.

In May 2016 Padma and I attended a conference in honor of my 70th birthday. There were more than 60 participants.
