Dr. Leigh Greathouse is an Assistant Professor of Nutrition Sciences at Baylor University. Before coming to Baylor, Dr. Greathouse received her masters degree in exercise and sports nutrition from Texas Woman’s University. She went on to obtain a Ph.D. In molecular carcinogenesis at University of Texas and MD Anderson Cancer Center, where she studied the effects of early life exposure to dietary and environmental xenoestrogens on development of reproductive tract disease. Dr. Greathouse continued her research in cancer prevention at the National Cancer Institute, where she completed her masters in public health at Johns Hopkins School of Public Health and postdoctoral fellowship in cancer prevention. While at the NCI, her research was focused on the impact of obesity and the microbiome on lung cancer risk. At Baylor, she continues this research where her laboratory focuses on understanding how the relationship between diet, obesity and the microbiome impact risk for colon cancer.


The focus of my laboratory is on elucidating the relationship between diet, the microbiome and colon cancer etiology. Our goal is to 1) delineate the dietary factors that modify the microbiome and its function, 2) develop microbial multi-omic classifiers that improve stratification of patients for colon cancer treatment, and 3) identify key functional pathways and mechanisms of the microbiota-host communication, including nucleic acid sensing cell receptors that control inflammation. Ultimately, our goal is to discover microbial and metabolic targets for the development of clinical tools to improve the treatment and reduce mortality from colon cancer.

What teaching at Baylor means to me.

Three events in my life have shaped my passion for teaching in the field of nutrition and cancer prevention, my strong belief in the power of 'living a healthy lifestyle as the norm' for prevention of disease, my battle with cancer and my faith. Baylor University gives me the opportunity to integrate all these experiences to not only deliver knowledge but also faith-based perspective that challenges students to examine their understanding of the intersection of science and faith.
