Robert R. Caldwell is an American theoretical physicist and Professor of Physics and Astronomy at Dartmouth College. His research interests include cosmology and gravitation.[2] He is known primarily for his work on theories of cosmic acceleration,[3] in particular dark energy, quintessence,[4] and the Big Rip scenario.[5] [6]


Caldwell received an A.B. from Washington University in St Louis in physics and French in 1987, and a Ph.D. from the University of Wisconsin-Milwaukee in 1992. He was a postdoctoral fellow at Fermilab (1992-4), the University of Cambridge (1994-6), the University of Pennsylvania (1996-8), and Princeton University (1998-2000). He has been on the faculty of Dartmouth College as an assistant professor (2000), associate professor (2005), and full professor (2010).[7] He was elected Fellow of the American Physical Society in 2008.[8]
