I work for the Clinical Trials Group within the Applied Clinical and Materials Science Research Programme. My main research interests are investigating the potential of oral healthcare products to reduce the pain of dentine hypersensitivity as well as reducing dental wear. I am involved in the running of in situ clinical trials as well as many in vitro studies. My original qualification was in Dental Technology so I still have an interest in the properties and development of dental materials. My PhD work investigated Ni release from NiCr alloys when compared to custom prepared physical vapour deposited thin films.
