Our Mission







Gut microbiota, which consists of approximately 1000 bacterial species has a tremendous impact on the biological functions of the host. Our research focuses on the gut microbiota - immune cells interactions of human, rodents, non-human primates and Drosophila flies. 


We aim to identify specific intestinal bacterial species that influence the host immune cells by inducing their functions and differentiation. By unraveling the mechanisms and key bacterial molecules, we strive to develop therapeutic intervention for healing wide-array of intestinal dysibiosis, such as inflammatory bowel disease, auto-immune diseases and allergy. 


If you're going to try, go all the way.

Otherwise, don't even start.
