Personal Statement:

The precise organization of synapses in the brain anatomically define and link the neural circuits that give rise to all our thoughts, emotions and behaviors. While synapse formation is necessary for the initial establishment of neural circuits, the process of refinement is critical for the specificity and maturation of all neural pathways. Our research seeks to understand mechanisms that govern the maintenance and elimination of synapses in the central nervous system. We utilize various molecular, cellular and behavioral approaches to tease apart the genes that shape the synaptic landscape throughout the lifespan.
