PhD (University of Illinois at Urbana & Champaign)

Assistant Professor, Department of Neuroscience (NS)

Dr Sungchil Yang achieved PhD in the department of molecular and integrative physiology, University of Illinois at Urbana & Champaign, studying a biophysical role of individual auditory neurons (from cochlear nucleus to auditory cortex) in auditory information processing under the supervision of Dr Albert S. Feng. Then, Dr Yang joined Helen Wills Neuroscience Institute of University of California at Berkeley as a postdoctoral fellow, studying mechanisms of an auditory phantom pain, tinnitus, with Dr Shaowen Bao. His research regarding the sensory system continued in Center for Integrative Neuroscience of University of California at San Francisco as a research associate, studying a role of axon initial segment of auditory neurons in information processing and a cellular basis of perceptual learning with Dr Kevin J. Bender and Christoph E. Schreiner, respectively. Then, he joined the Department of Biomedical Science in City University of Hong Kong.

Research Interest

A fundamental question in neuroscience is how a neuron processes innate and environmental cues in order to produce behaviorally relevant outputs. The several hypotheses how the inputs are stored, adapted, and learned in our brain have been proposed, yet their working models remain to be explored. For this, we study both the auditory systems (for mechanistic understanding of sensory learning process) and hippocampus (for cellular mechanisms of brain memory operation). Toward this end, we are performing 3D digital holography, two-photon imaging, voltage-sensitive dye imaging, and in vivo whole-cell recording. With these modern techniques, our research will reveal how our brain optimally captures and modifies information. This research will be eventually applied to cure information processing disorders embedded in several brain diseases such as autism, depression, schizophrenia, epileptic seizure, neuropathic pain, and tinnitus.
