Professional Interests

The goal of my research is to delineate the multiple fields of auditory and auditory-related cortex, identify their functional connectivity, and clarify the roles that each of these regions play in the neural processing of speech and other complex hearing phenomena. The three arms of my research career, coupled to my clinical career arms, make me ideally suited to contribute to this academic endeavor. Pertaining to the first arm, I was among the first investigators to rigorously examine auditory cortical mechanisms of speech processing in an animal model. Previously, it had been thought that animals would make poor models for this uniquely human process. My colleagues and I demonstrated that auditory cortical activity could explain many of features of speech processing, such as the neural events associated with the categorical representation of the voice onset time parameter, in the non-human primate model. This line of research has expanded over the years to address many of the key issues in auditory neuroscience, including clarifying neural mechanisms underlying auditory scene analysis, musical consonance and dissonance, pitch, and the mismatch negativity component of the human auditory evoked potential. We have also been among the first to demonstrate the close correspondence between monkey auditory cortical activity and that recorded directly from the human auditory cortex using intracranial electrodes. While I have retired from this research arm to increase my role on this project and pursue my mandate to help lead the new program of intracranial recordings in children at U Iowa, my animal research background helps ground this project in tenets of basic auditory cortical physiology.

The second arm of my research has been as co-investigator on this long-standing project. Working with the University of Iowa investigative team, I have been a major contributor to their intracranial studies that have helped delineate fundamental features of human auditory cortical physiology. In the last several years, working with Dr. Nourski as co-first author on multiple papers, we have identified the relative modulations of core and non-core auditory cortex by attention, and the role of these fields and auditory-related cortex including the middle temporal gyrus, supramarginal gyrus, and prefrontal cortex in word object formation and selection and in predictive coding mechanisms.

The third arm of my research, in collaboration with Dr. Elyse Sussman, and more recently, Dr. Monica Wagner, has focused on clarifying the maturation of cortical auditory evoked potentials and the effects of language experience on cortical speech processing. Finally, my 30 years of clinical experience in child neurology and clinical electrophysiology has made me keenly aware of multiple types of developmental language disorders and normal and aberrant features of the electroencephalogram. These experiences allow me to frame research questions in a translationally relevant way.
