Research Projects
 We are interested in the mechanism of cell growth and division. We have adopted multiple methodologies and model systems, such as high-resolution live cell microscopy in animal, plant, fungal, and macroalgal cells and in vitro reconstitution. Currently we conduct marine cell biology in Sugashima Marine Biological Laboratory (NU-MBL) and plant cell biology in Nagoya.
