Dr. Greathouse’s research interests include diet, inflammation, the gut microbiome, and colon cancer. Specifically, she is interested in diet and gut microbiome interactions that impact inflammation, obesity, and colon cancer treatment outcomes. As part of this research, she is focused on understanding the underlying mechanistic principals that govern host-microbiome communication and homeostasis. Dr. Greathouse applies machine learning algorithms, bioinformatic tools, and ecological statistical methodology to cohort studies and large datasets to identify biomarkers. She also uses molecular biology techniques to test these biomarkers for causative relationships. As a cancer biologist and dietitian, she collaborates with internal and external research teams to identify dietary and microbial factors that can be used to prevent disease and improve health outcomes related to chronic inflammation.
