We study about reproductive and developmental biology of mammal (cattle, pig and mouse), and we also focus on improvement of reproductive and developmental engineering methods. We research about

(1) Mechanism of mammalian spermatogenesis and spermiogenesis.

(2)  Mechanism of fertilization and the early development.

(3) Generation of novel experimental animals by genome editing.

(4) Effects on reproduction and development induced by early exposure of environmental chemicals.
