Previously, my research focused on the impact of the microbiome on host immune responses during homeostasis in zebrafish and the role of the microbiome in colorectal cancer development using mouse models. I’m interested in how the host and microbiome respond to environmental factors such as medications or diets and how these perturbations contribute to Clostridium difficile infections and colorectal cancer development.
