    Collapse Overview
    The scientific area to which I have devoted most of my work is stem cell research. I am interested in signaling circuits that might regulate the stem/progenitor cell pool(s) within epithelial tissues, which are responsible for homeostatic maintenance and regeneration after injury. Uncovering key signals for stem cell proliferation and differentiation will provide new insights useful for disease treatments and regenerative medicine.
