Stephon Alexander

Stephon Alexander is a professor of physics at Brown University and the 2020 president of the National Society of Black Physicists.

Alexander is a specialist in the field of string cosmology, where the physics of superstrings are applied to address longstanding questions in cosmology. In 2001, he co-invented the model of inflation based on higher dimensional hypersurfaces in string theory called D-Branes. In such models, the early universe emerged from the destruction of a higher dimensional D-brane which ignites a period of rapid expansion of space often referred to as cosmic inflation.

He is also a jazz musician and released his first electronic jazz album with Erin Rioux. The author of Jazz of Physics, Alexander lives in Providence, Rhode Island.
