SHORT BIOGRAPHY
Martyn Cobourne graduated from King’s College London School of Medicine and Dentistry in 1990.
After a series of junior hospital appointments in Bristol and London he undertook specialty training in orthodontics at King’s College Hospital, obtaining his Membership in Orthodontics in 1997. This was followed by a Medical Research Council Clinical Training Fellowship in 1998, and a PhD in Developmental Biology at the United Medical and Dental Schools, University of London (2002).
Martyn was appointed as a Senior Lecturer and Hon Consultant in Orthodontics at King’s College London Dental Institute in 2004 and promoted to Professor of Orthodontics in 2011. He became Academic Head of Orthodontics in 2016 and currently runs the Specialist Training Programme in Orthodontics at King’s College London.
His research is primarily focused on the role of molecular signaling pathways during early development of the head and face and he runs a laboratory-based research group in the Centre for Craniofacial Development & Regeneration at KCL.
He is also interested in the effectiveness of contemporary orthodontic treatment interventions and has led a number of randomized controlled trials investigating treatment efficiency.
He has published 150+ peer-reviewed articles and is the author of three successful orthodontic textbooks.
He was Director of Research at the British Orthodontic Society (2012-2016) and is currently Editor-in-Chief of the Journal of Orthodontics and an editorial board member of Scientific Reports.
He is Junior Vice-Dean of the Board of Faculty of Dental Surgery at the Royal College of Surgeons of England and a full member of the North Atlantic Division of the US Angle Society.
