Introduction
I am an ENT surgeon and head of the Center for Audiology and Hearing Implants Leiden (CAHIL) and the LUMC Expert Center for Rare Ear Diseases. From 2005 to 2023 I was also a trainer of the ENT residents in the Leiden OOR.
In 1983 I became a physical engineer at TU Delft (cum laude), in 1988 a medical doctor (cum laude). In 1994 Iwas certified an ENT consultant in Leiden, where I also received my PhD cum laude in 1995. In 1999 I founded the Leiden cochlear and auditory brainstem team, which, in close connection with translational scientific research, has now performed more than 1,500 implantations. I have been a professor in Leiden since 2005, and since 2023 I have also been a Medical Delta professor with an appointment at TU Delft.
My research focuses on (neuro-)otology and audiology, with special attention to technical, medical, and social aspects of cochlear implants. I have now published more than 200 peer-reviewed articles and have acted as a PhD thesis supervisor more than 25 times.

Scientific research
I have conducted research on cochlear implants (CIs), electrical inner ear prostheses for the severely hearing impaired and deaf, for over 35 years. The topics range from computer modeling, speech coding (also with artificial intelligence, AI), imaging (CT, MRI) and electrode designs to social-emotional aspects. For my dissertation Cochlear Implants – A Modeling Approach, I received several prizes. In 1996 I received the C.J. Kok Award.
My research is embedded in the LUMC innovation theme Neuroscience and in the national consortium NeuroTech-NL. Recent grants in the context of this consortium are the NWO CrossOver project INTENSE (14M€), in AI-driven front end processing techniques for CIs are being developed for better speech understanding in noise and the TEMPORAL project , 1M€, on fine structure coding in CIs using a combination of computer modelling, AI and psychophysics.
