Caroline Um, PhD, MPH, RD

Post-doctoral fellow


As a post-doctoral fellow, Caroline Y. Um investigates associations of food and nutrients in relation to colorectal cancer risk. She has co-led a pilot study on stool collection methods that will inform the future collection of stool samples among CPS-3 participants and enable the study of the gut microbiome.


Um aims to improve dietary behaviors and inform dietary guidelines to help reduce colorectal cancer incidence. Much of her research focuses on associations of specific foods and nutrients, such as processed foods, whole grains, and fiber, with colorectal cancer risk.

Additionally, Um is interested in how the gut microbiome and biomarkers of intestinal permeability and inflammation may be modified by dietary exposures to affect colorectal cancer risk.
