With the approaches of mathematical sciences, we are working on cell and developmental biology questions. In particular, among early developmental processes we are interested in (1) polarity and axis formation of cell and body, (2) directional and collective cell migrations, (3) morphogenesis of epithelial sheets, and (4) cell differentiation. Through the collaboration between experiment and theory, we are integrating experimental data, mathematical models and theories to quantitatively describe those processes and understand the mechanisms.

Keywords: Asymmetry: Polarity, Axis. Directional migration: Chemotaxis, Collective migration. Morphogenesis: mechanics, growth, rearrangement.
