Research Interests

Cell-cell communication is the bandmaster that orchestrates an amazing transformation of single cell zygote into many different types of cells and organizes them into complex patterns within the emerging body plan in a developing embryo. Our laboratory aims to understand how do cells in multicellular organisms communicate with morphogenetic signals to coordinate and organize themselves into complex patterns.
