Jessica Chubak, PhD, is an epidemiologist who works to improve cancer diagnosis, treatment, control, and survivorship. She contributes to several national collaborations that are finding practical, efficient, effective ways to screen for cancer, especially colorectal cancer. She also studies how common medications affect cancer risk and recurrence. Intrigued by how pets positively affect health, Dr. Chubak is studying animal-assisted activities in clinics and hospitals where children get treated for cancer. Dr. Chubak’s methodological research focuses on the use of administrative and electronic health record data in epidemiologic and health services studies.
Dr. Chubak joined KPWHRI in 2007, bringing expertise in epidemiologic methods, pharmacoepidemiology, and cancer. Awarded a Fulbright graduate student grant, Dr. Chubak pursued her master's degree in bioethics and health law in New Zealand before completing her PhD in Epidemiology at the University of Washington (UW). Dr. Chubak is an affiliate associate professor in the Department of Epidemiology at the UW School of Public Health, where she enjoys guest-lecturing and getting to work with students.
