Short Biography

I am interested in how cortical circuits mature, particularly during developmental windows of unique plasticity. During my thesis work at UCSF, I investigated the role of gonadal hormones in the maturation of inhibitory neurotransmission and dendritic spine dynamics in the frontal cortex of adolescent mice. In my postdoc work in the Nedivi lab, I will explore the dynamics of genetically labeled synapses and their activity-dependent selection during the critical period for ocular dominance plasticity in mice. Ultimately, I hope to contribute to our knowledge of how excitatory and inhibitory circuits are formed and refined in the context of experience during specific developmental windows.
