Paul M. Harari, MD


Dr. Paul Harari is a radiation oncologist and chairman of the University of Wisconsin Department of Human Oncology. As faculty of the UW School of Medicine and Public Health and a member of the UW Carbone Cancer Center Senior Leadership Council, Dr. Harari is deeply committed to the leadership of multidisciplinary clinical, teaching and research teams. He recently served as President and Chairman of the Board of the American Society of Radiation Oncology (ASTRO) with a major focus on highlighting the tremendous power and precision of radiation to heal, cure, image, and improve human health and quality of life.

According to Dr. Harari, a unique and highly appealing aspect of radiation oncology is the opportunity for close collaboration between technology, biology and clinical medicine. Many of the advances in the field involve multi-investigator teams working together to achieve new milestones. For any patient, cancer is a frightening diagnosis. But Dr. Harari notes that cancer cure rates are gradually increasing along with improved preservation of functional and cosmetic outcomes.

At UW Health, our radiation oncologists have cared for thousands of patients with complex cancers. While each patient is unique, there is great confidence in knowing we have cured patients with each type of cancer before.

Through our research and clinical trials, we are not only curing more patients here in Wisconsin, we are impacting cancer treatment techniques around the world. We have the opportunity to influence cure rates for cancer patients around the globe.

    Research and publications

    The overall theme of Dr. Harari’s research program is to improve treatment outcome for patients with head and neck cancer (HNC). Areas of particular research emphasis include the interaction of molecular growth inhibitors combined with radiation and the use of conformal radiation treatment techniques to reduce normal tissue toxicity. Dr. Harari serves as Principal Investigator (PI) for the UW Head and Neck Cancer SPORE Grant, a $15 million dollar effort to improve outcomes in HNC. The UW is currently one of four centers in the nation with a NIH HNC SPORE Grant. Dr. Harari serves as PI for a series of national and international HNC clinical trials that have changed global practice for patients with HNC.
