Professional background

Consultant ENT and skull base surgeon - clinical lead for auditory implants

I have completed my higher surgical training in the North Thames region in London in all aspects of elective and emergency otolaryngology. I have trained in different centres of excellence such as Charing Cross, The Royal National ENT & Eastman Dental Hospitals, The National Hospital for Neurology and Neurosurgery (Queen's Square) and the Northwick Park hospitals.

I have experience in all aspects of surgery of the ear, nose and throat. I sub-specialise in the field of cochlear implantation as well as middle ear and mastoid surgery. I have obtained a higher degree (MD) in the field of cochlear implantation. I worked in three cochlear implant centres in the UK.

I am currently a cochlear implant surgeon at the Royal National ENT & Eastman Dental Hospitals/ UCL cochlear implants programme in London. I am also a lateral skull base surgeon at the National Hospital for Neurology and Neurosurgery.
