The global oncology community is mourning the loss of Dr. Maura L. Gillison, the internationally recognized medical oncologist and molecular epidemiologist whose groundbreaking research transformed the understanding and treatment of human papillomavirus (HPV)-associated head and neck cancers. Gillison died on June 21, 2026, at the age of 61, following a battle with small bowel cancer. She passed away peacefully at her childhood home in Willoughby, Ohio, surrounded by her family, according to her husband, Dr. David E. Symer.
Gillison was widely regarded as one of the most influential physician-scientists in modern oncology. Through pioneering research conducted while at Johns Hopkins University, she became the first investigator to establish that a significant subset of oropharyngeal and head and neck cancers is caused by HPV rather than tobacco and alcohol alone. Her discoveries fundamentally changed cancer diagnosis, treatment strategies and prevention efforts worldwide, eventually contributing to expanded recommendations for HPV vaccination.
At the time of her death, Gillison served as Professor of Medicine in the Department of Thoracic/Head and Neck Medical Oncology at The University of Texas MD Anderson Cancer Center. Despite battling cancer herself, colleagues said she continued leading laboratory meetings and mentoring researchers until just days before her passing, remaining devoted to advancing cancer research and improving patient care.

Born in Canada, Gillison spent portions of her childhood in Canada, the United States and Mexico before her family settled in Ohio in 1974. She graduated from Hathaway Brown School in 1983 before earning a bachelor’s degree in zoology from Duke University in 1987. She later received her Doctor of Medicine from Johns Hopkins University School of Medicine in 1991 and completed a Ph.D. in Clinical Investigation in 2001, where her early research laid the foundation for one of oncology’s most significant discoveries.
Her landmark work demonstrated that HPV-positive head and neck cancers represented a distinct disease with different biological behavior and patient outcomes. The discovery reshaped international treatment guidelines, influenced cancer staging systems and strengthened the role of HPV vaccination as a powerful cancer-prevention strategy. Her research also helped identify patients who could benefit from more personalized treatment approaches, ultimately improving survival and quality of life for thousands worldwide.
Throughout her distinguished career, Gillison received many of medicine’s highest honors. In 2021, the American Society of Clinical Oncology (ASCO) presented her with the David A. Karnofsky Memorial Award, the organization’s highest scientific recognition. In 2025, she shared the prestigious VinFuture Grand Prize with fellow researchers for discoveries that advanced global understanding of HPV-related cancers. She was also elected to the National Academy of Medicine, the American Society for Clinical Investigation, and the Association of American Physicians.
Colleagues remembered Gillison as a brilliant scientist, compassionate physician and dedicated mentor whose influence extended far beyond her own laboratory. Leaders at MD Anderson, Johns Hopkins and ASCO praised her unwavering commitment to patients, her generosity toward trainees and her relentless pursuit of scientific discovery. Even while confronting her own illness, she continued supporting research teams and mentoring young investigators, leaving a legacy that will shape oncology for generations to come.
Gillison is survived by her husband, Dr. David E. Symer, their daughters, Sanna and Lia, her parents, siblings and extended family. A memorial celebration is being planned, while colleagues have also established a research fund dedicated to completing the ongoing scientific projects she championed. Her extraordinary contributions to medicine continue to influence cancer prevention, research and patient care across the world, ensuring that her legacy will endure for years to come.
