Research interests:

My research continues to be within the field of dental metrology and the application of measurement to various aspects of clinical dentistry using precise methodology.

This work includes studies in areas such as:

 

  • The development of measurement strategies
  • Finite Element Analysis of stresses within restorations
  • Assessment of quality of tooth preparations to receive a variety of restorations e.g. crowns, veneers, onlays
  • Fit of restorations
  • Wear of restorations

I continue to lead Dental Metrology Research Group within Adult Oral Health. The other members of the Group are: KG Seymour, Lifong Zou and GP Cherukara. We have collaborations with Renishaw plc, UK , Huddersfield University , UK , National Physical Laboratory, UK and the Technical University of Vienna, Austria.
