Curriculum vitae (CV)




Research interests and experience

  • Cancer control: epidemiology; breast cancer; medication use; survivorship; secondary prevention; quality of life; automated data collection; screening
  • Health services & economics: chronic illness management; translation of preventive care research into clinical practice
  • Medication use & patient safety: pharmaceutical outcomes research; validation of pharmacy data resources

Jessica Chubak joined Group Health Research Institute (GHRI) in 2007 with a passion for epidemiology and improving health care. With expertise in epidemiologic methods, pharmaco-epidemiology, and cancer, she is working with the Institute's cancer researchers to explore new inquiries in cancer screening and survivorship.

Dr. Chubak serves as the GHRI site principal investigator for the HMO Cancer Research Network. She also participates in several projects on medication use and cancer risk and prognosis. She is especially interested in evaluating programs and translating research into practices that improve health and health care.

Awarded a Fulbright graduate student grant, Dr. Chubak pursued her master's degree in bioethics and health law in New Zealand. This unique background has helped shape her commitment to moving research innovations into daily practice, especially for cancer survivors. She is building a research program in cancer screening and survivorship focused on preventing cancer death, recurrence, and late and long-term adverse effects of cancer treatment. She aims to develop epidemiologic methods for large-scale research on cancer screening and care management for cancer survivors.

Dr. Chubak is an affiliate assistant professor in the Department of Epidemiology at the University of Washington School of Public Health and serves as co-chair of GHRI’s Scientific Policy Committee. A member of the American Society of Preventive Oncology and the Society for Epidemiologic Research, she also serves as a peer reviewer for a dozen journals, including Medical Care, the Journal of Oncology Practice, and the Journal of Clinical Epidemiology.
