Project Description


Project description:

Cochlear implants (CIs) are advanced neuroprostheses that can restore hearing in individuals with profound hearing loss. These devices function by directly stimulating the auditory nerve through electrical pulses delivered via a small-scale electrode array implanted within the cochlea, the human hearing organ. Our research focuses on identifying objective biomarkers of both neural and tissue health using Evoked Compound Action Potentials (ECAPs), which are synchronized responses generated by auditory nerve fibers in response to electrical stimulation.

Typically, raw ECAP signals are pre-processed to eliminate artifacts such as random noise and drifts, which are often considered unwanted disturbances. However, in our project, we aim to mine these ECAP artifacts to uncover potential biomarkers that could provide insights into tissue health within the cochlea. Our goal is to extract valuable information from these previously overlooked signal components and correlate our findings with other measurement modalities, such as inner ear impedance.

We are seeking a motivated student with a strong interest in digital signal processing and biomedical applications to join our team in analyzing ECAP signal artifacts. This position offers an opportunity to work in a highly interdisciplinary environment at the Rechts der Isar hospital, located in the heart of Munich, where you will be at the intersection of cutting-edge technical research and clinical practice.
