We study the neural circuits that make auditory cognition possible. Our goal is to understand how we assign meaning to sounds, how we attend to sounds or ignore them, how we remember them, and how disorders of the brain can affect these processes.
Of particular interest is how our responses to sounds can change depending on context, a phenomenon called behavioral flexibility. Behaving appropriately after changes in context requires that organisms rapidly modify their expectations, associations between cues and rewards, or attentional state. Our lab investigates these cognitive processes by addressing three questions:
  • What happens to the speed and accuracy of behavioral responses after a change in context?
  • Where in the brain is information selected and re-routed to allow for different interpretations of the same stimulus?
  • How do neural circuits implement this flexibility?
In our experiments, we use techniques such as optogenetics, electrophysiology, and two-photon imaging, to monitor and manipulate neuronal activity of specific cell types in behaving rodents, together with theoretical and computational approaches, to uncover the mechanisms that underlie flexible behaviors.
We are committed to providing an inclusive environment and to celebrate the diversity of our researchers. We welcome the unique contributions every member of the lab can bring because of their education, culture, ethnicity, race, sex, sexual orientation, gender identity and expression, nation of origin, age, religion, or disability.
