Paul Sondel, MD, PhD, is the Reed and Carolee Walker Professor in Pediatric Oncology at the University of Wisconsin – Madison. He volunteers in an advisory capacity with the Invenra team to help develop its preclinical pipeline assets; recent work in Dr. Sondel’s lab highlights the potential efficacy of tumor specific Treg depleters when combined with current state-of-the-art immuno-oncology therapies, including tumor-reactive monoclonals. A Milwaukee native, Dr. Sondel completed his undergraduate and graduate education at UW-Madison leading to a Ph.D. in Genetics (1975), with guidance from Bone Marrow Transplant pioneer, Fritz Bach, M.D. He received his M.D. magna cum laude in 1977 from Harvard Medical School, while beginning his research in tumor immunology. Following pediatric residency training at the Universities of Minnesota and Wisconsin, he joined the faculty of UW-Madison in 1980 in the Departments of Pediatrics, Human Oncology and Genetics. He was promoted to professor in 1987 and became leader of the UW Carbone Cancer Center's Program in Immunology and Immunotherapy in 1990, when he also became Head of the Division of Pediatric Oncology. Throughout his career, he has been a leader in scientific policy through multiple national committee roles, including The National Institutes of Health, The American Cancer Society, The Children's Oncology Group (COG), The National Cancer Institute, where he was a member of the Board of Scientific Counselors, and St. Jude's Children’s Research Hospital, where he was the Chair of their Scientific Advisory Committee and is now a member of their cancer center's external advisory board.
