Ken Grant, Ph.D.

Dr. Grant is the Chief of Scientific and Clinical Studies at Walter Reed National Military Medical Center.  Dr. Grant's research has been concerned primarily with the integration of eye and ear for speech perception in both normal and hearing-impaired populations using behavioral and neurophysiological measures. Current work in this area is focused on changes in cognitive load as a result of combining auditory and visual cues and the impact of age, hearing loss, and traumatic brain injury on one's ability to selectively attend to one or more targets in the presence of multiple competing auditory and visual sources.

 

Stephanie Kuchinsky, Ph.D. 

Dr. Kuchinsky is a staff reseracher at Walter Reed Military Medical Center. In addition to being an MNC faculty member, she is also an Assistant Research Scientist at UMD’s Center for Advanced Study of Language.The goal of Stefanie Kuchinsky’s research program is to evaluate and improve speech and text comprehension in adverse conditions. Using functional neuroimaging and pupillometry techniques, Dr. Kuchinsky investigates the sensory and attention systems that support speech-in-noise understanding with the goal of developing effective interventions that optimize both comprehension and cognitive effort.

 

Jonathan Simon, Ph.D. 

Dr. Simon is a professor at the University of Maryland, with a joint appointment between the Department of Electrical and Computer Engineering, the Department of Biology, and the Institute for Systems Research. His expertise is in applied and theoretical auditory neuroscience. The goal of his research is to understand how the auditory cortex processes complex sounds such as speech and other natural sounds using magnetoencephalography (MEG), because of its high temporal resolution (milliseconds), reasonable spatial resolution (millimeters), and silent operation. 

 

Shihab Shamma, Ph.D.

Dr. Shamma is a member of the University of Maryland faculty since 1984 when he started as an Assistant Professor in the Electrical Engineering Department. He is associated with the Institute for Systems Research. The goal of his research is the representation of the acoustic signal at various levels in mammalian auditory systems. This ranges from theoretical models of auditory processing in early and central auditory stages, to neurophysiological investigations of the auditory cortex, to psychoacoustical experiments of human perception of acoustic spectral profiles.

 

Jonathan Fritz, Ph.D.

Dr. Fritz has been an ISR research scientist since 2004, and an associate research scientist since 2009. He is also a researcher in the Section on Brain and Language at the National Institute on Deafness and other Communication Disorders at the National Institutes of Health. Dr. Fritz's research in task-related adaptive plasticity in auditory processing currently focuses on behavioral physiology studies of the ferret primary and secondary auditory cortex. He also is interested in the neurobiology of auditory attention, learning and memory as well as auditory perception, including psychophysical studies, perceptual and behavioral lesion studies, and neurophysiological studies of ferret frontal cortex and its role in top-down control of auditory processing.

 

Patrick Kanold, Ph.D.

Dr. Kanold studies the development and plasticity of the brain, in particular how periods of learning and plasticity are initiated and controlled. His work focuses on the development of the central auditory and visual system in particular on the role of early cortical circuits in brain wiring. He uses advanced neurophysiological, in vivo imaging, optogenetic, molecular and computational techniques. His work furthers our understanding of how prenatal and postnatal brain injury contribute to neurodevelopmental disorders such as cerebral palsy, epilepsy and schizophrenia.
