  • Summary Statement of Research Interests

    My lab studies vocal learning in songbirds as a model system for understanding basic mechanisms of neural development, learning and memory, and brain-behavior relationships. Our research program has made key discoveries about changes in the neural substrate for learned vocal behavior that occur during early development as birds learn the sounds used for vocal communication. For example, we have shown that a specific neural circuit in the basal ganglia is necessary for vocal learning in juveniles, and that single neurons in this circuit gradually become selectively tuned to the specific vocal sounds heard during development. Our work has helped to elucidate how the brain controls and produces behaviors (such as learned vocal utterances) and how early experience affects the development of neural networks. This research is an important part of understanding speech acquisition in children, normal brain function, and the brain’s response to injury, disease and aging. Among other projects, we are currently investigating the contribution of specific neural circuits to distinct aspects of vocal learning (such as perception and production, the role of auditory experience in sculpting neural circuits for vocal learning during sensitive periods of development, and the influence of sensory experience in regulating specificity of connections in neural networks.
