Robert R. Caldwell
Professor of Physics and Astronomy
Robert Caldwell is a theoretical physicist specializing in cosmology. His research addresses questions about the basic properties of the Universe. What is its history and future? What is its composition? What are the fundamental laws that govern its behavior? He has written scientific articles on topics such as dark energy, dark matter, the cosmic microwave background, gravitational waves, and the fate of the Universe.
He received a PhD in physics from the University of Wisconsin at Milwaukee in 1992, and has held research appointments at Fermilab, Cambridge University, the University of Pennsylvania, and Princeton University. He has been on the faculty of Dartmouth College since 2000.
He teaches both undergraduate and graduate courses at Dartmouth. His research students have gone on to become astronomers and physicists, professors and research scientists, doctors, bankers, and more. Off term, he gets to travel and do physics: in the photo, he’s taking a break from 2013 summer lectures to hike in the French Alps.
