The Simons Center for Geometry and Physics is a research center devoted to furthering fundamental knowledge in geometry and theoretical physics, especially knowledge at the interface of these two disciplines. The Simons Center is housed in its own building, and is part of Stony Brook University. Simons Center has strong scientific connections with the Stony Brook Mathematics Department and Yang Institute for Theoretical Physics.

The Center sponsors visiting research programs with focused activities, as well as weeklong focused research workshops in physics and mathematics. In addition there is a weekly SCGP Colloquium, geared for the more general math and physics community, as well as the Della Pietra Lecture Series, which brings world-renowned scientists to the Center, to raise awareness of recent and impactful scientific discoveries in the community.
