Research Interests

Gai and her neuroengineering lab have been dedicated to the cutting-edge technology of improving life quality of paralyzed or hearing-impaired patients. Her recent projects include brain-controlled wheelchairs, next-generation smart hearing aids, and infrared cochlear implants.

Labs and Facilities

Neuroengineering Laboratory The Neuroengineering Lab’s research combines behavioral, electrophysiological, and computational approaches to study functions and mechanisms of the mammalian auditory pathways in speech perception and sound localization. The lab’s first project involves simulating cochlear-implant hearing with a noise-vocoding technique. Learn more:

Honors and Awards

Gai's project on brain-controlled wheelchairs received the President Research Fund in early 2017.

Community Work and Service

Yan Gai became an assistant professor in Biomedical Engineering at Parks College in Fall 2014. Prior to joining SLU, she was a postdoc and neuroscientist at New York University and University of Wisconsin-Madison.
