Head of School of Medical Sciences
He was previously Director of the Institute of Human Development at Manchester and is a Professor of Child Health and Paediatric Endocrinology and honorary consultant at the Royal Manchester Children's Hospital and the Christie Hospital.
He graduated from Manchester University Medical School in 1984 (Distinction in Paediatrics), having obtained a first class intercalated degree in Physiology and Pharmacology in 1981.
Professor Clayton did his early paediatric training around Manchester before embarking on an academic career in Paediatric Endocrinology. He spent time at the University of Virginia, USA as a MRC Travelling Fellow in 1990-1991.
His primary research interest is centred on understanding mechanisms leading to disordered growth and development. His research group has always included a mixture of clinicians and scientists, working on projects from basic science through to clinical trials, with a strong emphasis on translational medicine.
Professor Clayton has served on the Councils of the British Society for Paediatric Endocrinology and Diabetes, the Society for Endocrinology (SfE, UK), the Growth Hormone Research Society and the European Society for Paediatric Endocrinology (ESPE).
He has organised and chaired a number of International Consensus meetings on aspects of paediatric endocrinology that have shaped world-wide clinical practice.
Professor Clayton has been honoured with medal lectures for the SfE, ESPE and the Australian Endocrine Society and guest lectures for the American Endocrine Society, and Paediatric Endocrine Societies in Europe, South America, Japan, India and Korea.
He was appointed a consultant at the Royal Manchester Children’s Hospital in 1994, overseeing the endocrine service developing from two consultants into a team of seven with four specialist endocrine nurses.
In collaboration with Alder Hey Children’s Hospital, he established Manchester as one of two centres in the UK providing care for babies with the rare and very serious condition of congenital hyperinsulinism.
Professor Clayton also holds a consultant post at the Christie Hospital, where he sees children with endocrine late-effects from cancer treatment.
In 2005, he led the successful bid to establish an NIHR Medicines for Children Local Research Network (LRN) in Greater Manchester, Lancashire and South Cumbria and was its Director from 2006 to 2015.
He has also been involved with the Greater Manchester Comprehensive Local Research Network since its inception in 2007, as a member of the Executive and as Associate Director between 2013 and 2015.
