Stephon H. Alexander

STEPHON H. ALEXANDER is an associate professor of physics at Haverford College. He received his Ph.D. in physics from Brown University in 2000, with a dissertation titled “Topics at the Interface between String Theory and Cosmology.” From 2000 to 2002, he held a postdoctoral fellowship from PPARC (the Particle Physics and Astronomy Research Council of the United Kingdom). He recently won the National Science Foundation CAREER award and was elected a National Geographic Emerging Explorer. 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.
