Understanding Intestinal Barrier Function in Health and Disease
We study how the intestinal barrier maintains homeostasis, responds to environmental stressors, and recovers after injury. By examining epithelial–immune interactions, our work aims to define the mechanisms that preserve gut immune balance in health and disease.
Explore Epithelial–immune Interactions
We investigate how the intestinal barrier maintains balance between digestion, nutrient absorption, and immune regulation. By studying the interactions between epithelial cells and the immune system, we aim to understand how the gut responds to stress, recovers from injury, and preserves homeostasis. Our research combines cellular and molecular approaches with collaborative expertise, driving insights that could inform strategies for maintaining gut health and treating disease.
