He has published on the effects of reflux on the throat, as well as on many aspects of head and neck disease. In clinic, he uses the latest in imaging technology to view the throat of patients with voice, swallowing and breathing problems. He also sees patients with chronic cough and is an expert in treating pharyngeal pouches, with 75% of my practice being patients referred from other consultants due to the difficult nature of their problems.
He is a highly experienced expert witness available for legal cases involving the head and neck, voice and throat issues.
