Summary

My research explores the relationships between diet and the human gut microbiome in health and disease using novel computational methods for dietary data. My current focus areas include 1) analysis of diet and microbiome after dietary interventions, 2) methods development for dietary data analysis and visualization, and 3) understanding the interactions between foods, microbes, and fungi during different stages of development. I am interested in exploring how diet and the microbiome interact to influence chronic diseases including prediabetes, diabetes, and cancer.
