Bio

Throughout my career, I have striven to understand how neural circuits allow reliable auditory perception. In my graduate work at Duke University, I studied songbirds, whose ability to sing is essential for reproductive success. I used in vivo intracellular recordings to uncover mechanisms underlying neural selectivity for song. During a postdoc at Cornell University, I worked with an insect whose reproductive success relies on locating chirping crickets (on which to deposit eggs) while avoiding predation by calling bats. I measured neural and behavioral responses allowing the fly to make this distinction. For my postdoc at New York University, I began work which I continue in my own lab: I study Mongolian gerbils, which communicate at frequencies similar to those in human speech. We research how early auditory experience changes neural circuitry to allow accurate auditory perception. My research on neural mechanisms underlying perceptual effects of hearing loss is funded by NIH.

AREA OF EXPERTISE/RESEARCH INTERESTS

Early life experiences have lasting effects on neural circuits, which can influence a wide range of abilities and characteristics. Childhood hearing problems, particularly in stressful environments, affect our ability to optimally understand speech later in life. My research applies neurophysiological, neurochemical, behavioral, and quantitative techniques in an animal model to understand how developmental hearing loss and stress change the neural circuits necessary for auditory perception. This work lets us identify interventions to remediate perceptual deficits arising from these early detrimental experiences.
