Timothy Kennedy’s laboratory is investigating the molecular mechanisms that direct neural development and how such mechanisms influence the organization and plasticity of the mature mammalian central nervous system. These studies aim to identify the biochemical signals that direct cells and axons to move, as well as the target-derived signals that instruct them to stop once they reach their goal and to make appropriate connections with neighboring cells.

Laboratory members are researching the cellular and molecular mechanisms that direct axon guidance, oligodendrocyte precursor migration, myelination, synapse formation and synaptic plasticity.
