I study how the brain processes speech sounds.

Currently, I am using electrocorticography (ECoG) to directly measure neural dynamics of learning-induced changes from the surface of the human auditory cortex. Previously, I have used a combination of functional and structural neuroimaging methods to examine neural correlates of individual variability in speech sound learning.
