Theoretical Atomic Physics

The motivation for Dr. Drake's research is to develop new tools to probe the properties of atoms by combining the high precision theoretical techniques he and his students have developed with the high precision measurements made possible by the modern methods of laser spectroscopy. He works closely with experimental groups around the world on projects such as the use of laser spectroscopy to measure the size of short-lived atomic nuclei (especially halo nuclei), and to improve our knowledge of the values of the fundamental constants. The significance of his work has been recognized by the award of numerous prizes and he receives the largest NSERC research grant in Canada for theoretical research in the area of general physics.
