STEPHON H. ALEXANDER is the Ernest Everett Just 1907 Professor of Natural Sciences at Dartmouth College. As a theoretical physicist, his research focuses on unresolved problems—such as the cosmological-constant or dark- energy problem—that connect cosmology to quantum gravity and the standard model of elementary particles. In particular, he uses observations in cosmology to both construct and test fundamental theories. He also reasearches connections between music and science.
From 2000 to 2002, he held a postdoctoral fellowship from PPARC (the Particle Physics and Astronomy Research Council of the United Kingdom). He has been awarded the National Science Foundation CAREER award and was elected a National Geographic Emerging Explorer.
