Duncan did both his undergraduate and graduate degrees at the University of Oxford in England, obtaining his D.Phil. in experimental atomic physics in 1987. Since then, he has held research positions at the University of Cambridge, the University of Virginia, and at the University of Illinois at Chicago, before coming to Colby College in 1992.

Duncan’s research interests include high resolution laser spectroscopy; ionization dynamics of Rydberg states of atoms; the interaction of super-high intensity laser pulses with atoms, molecules and solids; and atom cooling and trapping. His laboratory at Colby College contains apparatus for two different types of experiments. One apparatus is designed to perform spectroscopy experiments on atoms and molecules using diode lasers (the kind in your DVD player). Several students have been involved in this project, both as part of their senior thesis projects and as summer research assistants. In addition he has built constructed a neutral-atom trap in which gases can be cooled to just a fraction of a degree above absolute zero. Recently he received a grant from the National Science Foundation to support his research on dense clouds of ultracold gases.
