# Pierre Dubé

Pierre Dubé received his Ph.D. in physics from the University of Toronto in 1994.  He went on to be a postdoctoral fellow at JILA in Boulder, Colorado, with John Hall, and a postdoctoral fellow at TRIUMF, in Vancouver, Canada, with Otto Haüsser. Since 2000, he has been working at the National Research Council of Canada.  His main research interests include the development of ultrastable laser systems, the study of systematic frequency shifts in single-ion systems, and the development of high-accuracy single-ion optical clocks.
