Stephon Alexander focuses on theoretical cosmology, quantum gravity and particle physics. He has studied at Brown University and done postdoctoral research at Imperial College, London and at the Stanford Linear Accelerator Laboratory.

The research of Dr. Stephon Alexander primarily focuses on understanding the nature of dark energy in the universe, the origin of matter over anti-matter (baryogenesis) in the universe, the origin of large scale structure in the universe from fundamental theory, how space-time singularities, like the initial big-bang singularity are resolved, and how to test a theory of quantum gravity with observations in cosmology.

Alexander also plays jazz saxophone and sees improvisation as an extension of his scholarship.
