Robert Orr is one of Canada's leading experimental particle physicists, having made crucial contributions to discoveries in elementary particles. Through the development and exploitation of new experimental techniques, he has made seminal contributions to the study of the electroweak interaction, proton structure and heavy quark physics. Through his leadership, a team of 100 Canadian scientists is playing a significant role in the ATLAS experiment at the CERN Large Hadron Collider, a project designed to uncover the fundamental mechanism for mass and search for phenomena that would allow us to understand the properties of the basic forces.
