Research Interests:

Cell adhesion is essential to the development of nervous system, from neuronal migration to axon guidance and synapse formation, as well as the maintenance of neural integrity against environmental forces.  To understand how cell adhesion molecules function in such a wide spectrum of events, we focus on the L1 family of cell adhesion receptors, using genetic, molecular, and biochemical approaches to dissect their functions and mechanisms of action.  Mutations in the human L1CAMs can result in numerous neurological syndromes that include the L1 syndrome, autism, and susceptibility to addiction.
