Luc Van Immerseel, Ph.D.

Senior R&D and Neurophysiology Expert

Dr. Van Immerseel is a senior R&D and neurophysiology expert with over 20 years of experience in hearing, cochlear implants (CI) and Neuromodulation devices. He designed a new CI stimulation ASIC and multiple stimulation paradigms for Antwerp Bionic Systems, Philips Hearing Implants and Advanced Bionics Corporation. For several years he did research and development on the recording of evoked potentials with a combination of modeling, in vivo recording in animals and studies with CI patients. Thereafter, he developed software platforms for research in stimulation and recording for Advanced Bionics Corporation.
