Dr. Jackilen Shannon is a nutritional epidemiologist with a strong track record of investigation in the role of diet and nutrition in carcinogenesis. She joined Oregon Health & Science University in 2000. She completed a doctoral degree program in nutrition with a minor in epidemiology at the University of North Carolina, Chapel Hill, and an NIH-NCI postdoctoral training fellowship in cancer epidemiology at the Fred Hutchinson Cancer Research Center in Seattle, Washington.

Dr. Shannon’s  research focuses on using epidemiologic methods to investigate the role of bioactive food components in early carcinogenesis. The focus of this work has narrowed over the past five years from broad case-control studies with multiple dietary exposures to directed clinical trials and family-based association studies that target specific bioactive nutrients and their function in particular biologic pathways frequently dysregulated in early carcinogenesis. Breast and prostate cancer have been the model diseases within which this work has been conducted. As demonstrated through recently funded awards, Dr. Shannon’s efforts are targeted primarily at elucidating the potential chemopreventive effects of two bioactive dietary compounds, omega-3 fatty acids and sulforaphane.
