Dr Rizzardo has an outstanding record of achievement in the invention and. development of chemical methodologies relating to the molecular control of polymer architects produced by free radical polymerisation. Indeed, he is internationally acknowledged as a world leader, if not the world leader, in this field, which has the potential to revolutionize the way that polymers are made. Literally hundreds of papers from groups around the world are based on Rizzardo's work. In recognition of his standing he receives invitations to speak (plenary/keynote) at all the major meetings in polymer science that are held around the world, as well as some important meetings in free radical organic chemistry. In addition, he has been invited to deliver the prestigious Melville Lecture at Cambridge University (2000) and the Rauscher Lecture at the Rensselaer Institute in New York (2001). Awards for his work include the CSIRO Medal, the CSIRO Chairman's Medal, the RACI Australian Polymer Medal, and the RACI Applied Research Medal. He has an enormous citation rate in the literature.
