Ralph Weichselbaum, MD, is a radiation oncologist investigating tumor and host factors that limit metastasis and novel methods of treatment of metastasis. One of his most distinguished accomplishments includes when he and Samuel Hellman, dean of biological sciences at the University at the time, discovered oligometastasis, an intermediate state of metastasis that could be successfully treated and controlled. He and Hellman maintained that many patients with oligometastatic disease could be cured, depending on the extent of disease burden, with either surgery or targeted radiation therapy. This notion, the spectrum theory of metastasis, has slowly been accepted, backed by a mounting series of reports of successful treatments.
 
He has published more than 850 academic papers or reports across multiple fields. Throughout his career,  he has received numerous awards and honors. The American Society of Clinical Oncology (ASCO) honored Weichselbaum as the 2018 recipient of the David A. Karnofsky Memorial Award and, in that same year, the American Society for Radiation Oncology (ASTRO) awarded him with the Gold Medal, one of its highest honors. He is a member of the National Academy of Medicine and the Association of American Physicians.
 
Weichselbaum was born in Chicago, graduated from the University of Wisconsin in Madison, and attended medical school at the University of Illinois in Chicago. After medical school, he did his residency at the Joint Center for Radiation Therapy at Harvard University. He later joined the faculty there, rising quickly to associate professor status. In 1984, he was recruited to the University of Chicago to become Professor and Chair of Radiation Oncology. He is now the Daniel K. Ludwig Distinguished Service Professor, Co-Director of the Ludwig Center for Metastasis Research, and Director of the Center for Molecular Oncology.

Tara Henderson, MD, MPH, specializes in the diagnosis and medical treatment of patients with pediatric cancers. She has a particular interest in the care of childhood cancer survivors.
