About the Author

MIGUEL MAROTO is a MRC Career Development Fellow and Lecturer at the University of Dundee, UK. He received his PhD in Biochemistry and Molecular Biology from the Department of Biochemistry of the Universidad Autonoma of Madrid, Spain. His research interests include investigating the biochemical basis of different signalling mechanisms implicated in the acquisition of specific cell fates during vertebrate development. In recent years he has been involved in the analysis of the mechanism of the molecular clock in the control of the process of somitogenesis.

NEIL V. WHITTOCK gained his PhD in Human Molecular Genetics whilst working at Guys’ and St Thomas’ Hospitals in London, UK. His research focussed on developing diagnostic genetic tests for Duchenne muscular dystrophy before moving on to identifying genes involved in bullous skin disorders. He then continued his research as a postdoctoral fellow at the University of Dundee before arriving at the University of Exeter where he spent three years working alongside Dr Peter Turnpenny. The work at Exeter focussed on the identification of genes involved in human genetic disorders that affected the development of the spine and ribs, specifically the spondylocostal dysostoses. He now works as an Ambulance Technician in Devon, UK. and runs his own antique clock restoration business.
