Meet the Team


Prof Sian Ellard

Prof Sian Ellard is Professor of Human Molecular Genetics at the University of Exeter Medical School and also a Consultant Clinical Scientist at the Royal Devon and Exeter NHS Foundation Trust where she heads the Molecular Genetics Department. Sian’s research focuses on understanding the underlying genetic mechanisms of monogenic endocrine disorders including congenital hyperinsulinism and neonatal diabetes. (University profile).



Sarah Flanagan

Dr Sarah Flanagan

Dr Sarah Flanagan is a Sir Henry Dale Fellow and molecular geneticist whose research focuses on understanding the underlying genetic mechanisims of congenital hyperinsulinaemic hypoglycaemia. With Sian, Sarah leads the hyperinsulinism research work being undertaken in Exeter. Her interests include analysing genotype/phenotype relationships and employing next generation sequencing technologies to search for novel hyperinsulinism genes (University profile).

Dr Thomas Laver

Dr Thomas Laver is a post-doctoral research fellow and bioinformatician  at the University of Exeter Medical School. His research focusses on the analyses of next generation DNA sequencing data to identify novel genetic aetiologies for congenital hyperinsulinism. (University profile).




Dr Jayne Houghton

Dr Jayne Houghton is a Clinical Scientist within the department of Molecular Genetics at the Royal Devon and Exeter Foundation NHS Trust. Jayne’s work focuses on the clinical interpretation of genetic variants residing in genes known to cause hyperinsulinaemic hypoglycaemia, neonatal diabetes and Maturity Onset Diabetes of the Young.
