Current Research Interest:

The formation, maintenance, and rewiring of synaptic connections in the mammalian brain. In particular, how axonal innervations to postsynaptic targets are: (1) refined during brain development, and (2) reorganized in adulthood with learning and memory, and (3) with brain injury.
