Upen Patel successfully defended his PhD thesis on “KiloHertz ultrasound as a potential therapy for dental repair”, subject to minor corrections. Here is the successful Dr Patel with his external examiners Dr Meghji and Professor Irwin. His research looks at the use of ultrasound to repair cells and may have future implications on how we treat the damaged tissues in the tooth. Upen has already had two papers published from his research on this exciting subject. Well done Upen on a successful result!
