I am a Ph.D. candidate in Zoology at the University of Wisconsin-Madison with Dr. Lauren V. Riters. I study the neurobiology of vocal communication in songbirds, with a focus on the control of singing behavior across contexts. My main interest as a behavioral neuroscientist to understand the mechanisms of behavior incorporates elements of neurobiology, neuroethology, and neuroendocrinology.
In species that use vocalizations to communicate, individuals must produce vocalizations that are appropriate in a given context for effective social interactions. While the neural basis of vocal production is well-known for some animal groups, such as songbirds, it is not clear how the brain regulates vocal signals across contexts. My dissertation work examines the role that neurotensin, a neuropeptide involved in motivation and social behavior that strongly interacts with dopamine, may have in modulating context-specific communication. This research aims to enhance our understanding of the neural control of vocal communication, of the regulation of social behavior across vertebrates, and ultimately of the functional relationship between the brain, behavior, and environment.
