Positions

  • Professor, Departments of Medical Physics and Human Oncology, University of Wisconsin-School of Medicine and Public Health, Madison, WI.
  • Director, Medical Devices Focus Area, Morgridge Institute for Research, University of Wisconsin
  • Co-founder, Chairman of the Board, Tomotherapy Inc., Madison, WI

Research Interests

Dr. Mackie’s career has been focused on planning and delivery of radiation therapy to cancer patients. His group developed the 3-D treatment planning system that became the Philips Pinnacle treatment planning system, the most widely used radiation therapy treatment planning system in the world. His group was also the developer of tomotherapy, which is the marriage of a linac and a CT scanner. More recently, Rock has been active in development of a compact proton therapy machine for treating cancer.
