Using an “organ on chip” model of the cochlea for rapid drug assay, and to test new generations of cochlear implants

We have an interdisciplinary program with biomaterials, clinicians, surgeons, electrical engineers and chemical engineers to 3D fabricate cochleas with microanatomy similar to living cochleas, embedded with sensors that can sense current spread from cochlear implants, or ion gradients from various inner ear cell types that can generate them. Our goal is to develop these types of constructs, seed them with 3D cultures of various  inner ear cell types and examine how cochlear implants can activate auditory neurones, or how regeneration or pharmacologic support for hearing loss can be developed.  his is in order to develop the next generation of inner ear hearing loss therapies.
