Background

Dr. Xiaoquin Wang is a professor of biomedical engineering, neuroscience and otolaryngology at the Johns Hopkins University School of Medicine. He serves as director of the Tsinghua-Johns Hopkins Joint Center for Biomedical Research in Beijing, China.

His research aims to understand brain mechanisms responsible for auditory perception and vocal communication in a naturalistic environment.

Dr. Wang received his B.S. in electrical engineering at Sichuan University in Sichuan, China, and his M.S. in electrical engineering and computer science at the University of Michigan in Ann Arbor, Michigan. He completed his Ph.D. in biomedical engineering at Johns Hopkins, and subsequently conducted a postdoctoral fellowship in neurophysiology at the University of California in San Francisco.

He joined the Johns Hopkins faculty in 1995 as an associate professor, became an assistant professor in 2002, and accepted the title of ful professor in 2002.

Dr. Wang has won several awards and NIH grants for his research, and currently serves as principal investigator of the Laboratory of Auditory Neurophysiology in the Department of Otolaryngology. He has served on the editorial review boards for more than 20 academic journals in the field, has authored or co-authored several dozen peer-reviewed publications and has presented his work nationally and internationally.

Research Summary

Dr. Wang’s research focuses on the neural basis of auditory perception and vocal communication in a naturalistic environment. This includes research to reveal neural coding mechanisms operating in the cerebral cortex and how cortical representations of biologically important sounds emerge through development and learning. Perception and production of communication sounds (e.g., human speech and animal vocalizations) are among the most important behaviors of humans and many animal species, and are crucial for a species’ survival and well-being. Because of the complexity and behavioral importance of communication sounds, understanding their neural representations in the cerebral cortex will help reveal computational principles that the brain uses to process a wide range of sounds we experience daily such as speech and music. Understanding how the brain processes such sounds will provide invaluable insights into neural mechanisms underlying human language perception as well as how the brain functions during social interactions.
