Professor Maura L. Gillison spent her career asking questions that challenged conventional thinking, ultimately changing how doctors and researchers understand cancers of the throat. Her death on June 21, 2026, at age 61 marks the loss of a pioneering medical oncologist and molecular epidemiologist whose research had a lasting influence on cancer prevention and treatment.
Gillison was born January 4, 1965, in London, Ontario, and grew up in the Cleveland area after her family moved frequently during her childhood. She graduated summa cum laude from Duke University in 1987 before earning her medical degree from Johns Hopkins in 1991 and later completing doctoral training in clinical investigation.
Her groundbreaking research helped establish the connection between human papillomavirus, particularly HPV-16, and oropharyngeal cancer. Research published from her doctoral work and later in The New England Journal of Medicine helped demonstrate that HPV-related throat cancers were biologically distinct from cancers primarily associated with smoking and alcohol.
Gillison’s findings also influenced cancer staging, treatment research and public-health discussions surrounding HPV vaccination. She became a strong advocate for vaccinating both boys and girls against HPV, emphasizing its role in preventing future cancers.
Her career included research and academic positions at Johns Hopkins, Ohio State University and MD Anderson Cancer Center.
Gillison died at her childhood family home in Willoughby, Ohio, from a rare cancer of the small intestine, according to her husband, Dr. David E. Symer.
Her legacy lives not simply in scientific publications, but in patients better understood, clinicians better informed, and generations potentially protected through prevention. Her work changed the conversation about HPV and cancer—and its influence will endure.
