Brian Charles Chaboyer

Professor of Physics and Astronomy

Brian Chaboyer is an astrophysicist who studies stars and stellar populations. He has been at Dartmouth College since 1998. His undergraduate degree is from the University of Manitoba, (1987) followed by a MSc from Queen's University (Canada; 1989) and a doctoral degree from Yale University (1993). Brian came to Dartmouth after a postdoctoral fellowship at the Canadian Institute for Theoretical Astrophysics and a Hubble Fellowship at the University of Arizona.
