RESEARCH INTERESTS: 

Each neuron in the brain is capable of forming and maintaining thousands of connections with other cells. Most of these synapses have the remarkable capacity to change in the face of new external stimuli and throughout various stages of development. Such plasticity is vital for allowing an organism to properly mature, survive, and learn to interact with its environment. The overarching goal of my research is to understand the molecular mechanisms underlying changes in the brain during development, learning, and exposure to drugs of abuse. My group’s research spans three domains of plasticity: (1) developmental maturation of excitatory synapses in late adolescence; (2) activity-dependent changes in synaptic strength at mature synapses; (3) drug-evoked plasticity at excitatory synapses in response to substances like ethanol. Our work utilizes a combination of biochemical assays, anatomical tracing, immunofluorescent imaging, rodent behavior, and electrophysiology in acute brain slices from rodents.
