The Jin lab research focuses on the molecular genetic mechanisms underlying the development and function of the nervous system using the nematode Caenorhabditis elegans. The transparency, defined anatomy, and rapid life cycle of this organism greatly facilitate our studies at the subcellular resolution. Moreover, the entre cell lineage and connectome are known, enabling functional understanding at deep levels. Through forward genetic screening in combination with multi-layered molecular and cellular manipulations, we are discovering key molecules that play conserved roles in synapse formation, maintenance, and function, as well as those underlying adult axon regeneration. Our ultimate goal is to connect the studies of basic mechanisms to the understanding of human neurological disorders and neuronal repair.
