Rhys joined Newcastle University from Cardiff University in August 2017. He is an Honorary Consultant in Epilepsy at the Royal Victoria Infirmary. His research interests include the causes and consequences of epilepsy – primarily the genetic causes of the epilepsies. Understanding the genetic contributions to epilepsy have recently led to a number of medications being re-purposed to help control seizures, so called ‘precision medicine’. Rhys was the 2017 Royal College of Physicians Linacre lecturer, where he spoke about the risks and benefits of Sodium Valproate for women of child-bearing age. He is an Associate Editor of Practical Neurology, Web Editor of Seizure and is on the editorial board of Clinical Medicine.
