Dr. Frijns (1961) has a Masters degree in Applied Physics (Hons., 1983, Delft) and an MD degree (Hons., 1988, Leiden). In September 1988 he started with his research on cochlear implants in the ENT-Department of what now is called the LUMC. Between 1989 and 1994 he was educated to become an ENT-Specialist and from then on he was affiliated to this clinic as a staff member. In 1995 he completed his PhD thesis (Hons.), entitled Cochlear Implants – A Modelling Approach (promotor Prof.Dr. J.J. Grote, Leiden and co-promotor Dr. J.H. ten Kate, Delft). This thesis was awarded the 1995 prize of the Dutch ENT society, and the second prize (1995-1996) of the Dutch Biophysical Society. In 1996 he was awarded the C.J. Kokprijs 1994 of the Leiden University. Clinically he sub-specialised in (neuro-)otology. In 1999 he founded CIRCLE, the Leiden cochlear and auditory brainstem implant program, building on the growing body of translational research on the subject of his group. At present, CIRCLE has implanted more than 850 patients (adults and children), with outcomes ranking amongst the worlds best. Frijns is teacher in a number of post-academic courses and organized several international conferences. In 2005 he became professor in Otology and Auditory Physics on behalf of the Heinsius-Houbolt Foundation. From 2005 to 2010 he was Chairman of the ENT-department of the LUMC. Since January 2006 he holds the ordinary Chair of Otorhinolaryngology. At present he is Chairman of the Centre for Audiology and Hearing Implants at the LUMC.
