Research Interests:
(1)The evolution of vertebrate peripheral nervous system: investigating the origin of vertebrate neural crest and placodes using amphioxus system
(2)Development of a continuous laboratory culturing system and research resources for amphioxus in Taiwan.
(3)Germ cell formation and the molecular composition of germ plasm in cephalochordates

One of the specific questions I would like to address with amphioxus as a model system is the origin of neural crest. Arising at the neural plate border, vertebrate neural crest cells undergo an epithelial to mesenchymal transition (EMT) to become a migratory cell population that forms numerous differentiated cell types, including the craniofacial skeleton, much of the peripheral nervous system, and pigment cells of the skin. Evolution of the neural crest is a hallmark of vertebrates, responsible for many complex structures of the vertebrate head that are lacking in invertebrate chordates, like amphioxus. By comparing the genetic controls operating during development at the edges of the neural plate in embryos of amphioxus and traditional vertebrate models, we can start to pin-point which part of the gene regulatory network might have been changed over time.
