His research focuses on neurophysiology and perceptual studies in animals and humans to better understand sound processing within the central auditory system. This research guides the development of new stimulation devices for hearing restoration and tinnitus suppression. One project to test a new midbrain auditory prosthesis in deaf patients is currently funded by NIDCD U01DC013030 (Lead PI) and is in collaboration with the largest cochlear implant company, Cochlear Limited. Since arriving in Minnesota in 2009, Dr. Lim's lab has continued to perform translational research with clinicians and several companies, including one of the leading medical device companies in the world, Medtronic (located in Minneapolis).
