Biosketch                Top

Dr. Lin obtained his Ph.D. in Neurobiology from the State University of New York at Albany in 1996. He then moved to the Salk Institute at La Jolla, CA, as a postdoctoral fellow and research associate. He joined the faculty at the Department of Neuroscience in 2003.

        

Research                  Top

Research in Dr. Lin's lab is focused on understanding the cellular and molecular mechanisms underlying formation, maintenance and plasticity of synapses. Using mouse neuromuscular junction as a model, his laboratory  studies initial cellular/molecular events triggering synapse formation, and mechanisms regulating synaptic patterning and motor neuron survival during development, with approaches combining molecular biology, biochemistry, electrophysiology and mouse genetics.
