Research Interests

My main research interests in the field of dental materials science, with a focus on resin based dental materials and particularly their ability to cure and potential for breakdown.  I have previously undertaken projects involving the tooth restoration interface, antibacterial properties of dentine adhesives, 2 body wear and colour stability of aesthetic restorative materials.

I am also supervising a PhD student investigating the impact of orthodontic appliances on eating related quality of life.

We recently completed an innovative group MSc research project, investigating parents willingness to pay for orthodontic treatment across 3 hospital orthodontic departments.

I am also actively involved in pedagogical research. 

My PhD

My PhD was focused on the interaction between dentine adhesives and root surface caries. Resin based adhesives may provide a means of treating root surface caries in a non-invasive manner. The long term efficacy of adhesives in this role is determined by their ability to penetrate into the carious lesion, inactivate bacteria within the lesion and achieve an adequate degree of cure in the hostile environment. A variety of novel techniques involving Raman microspectroscopy, confocal microscopy, light microscopy and caries sampling techniques have provided a unique insight into this potential application. Biofilm formation on the surface of these resins has also been investigated.


I have recently obtained $5000 and loan of an iTERO scanner from AlignTechnology to support an orthodontic research project.

Two small grants supported my PhD studies - Oral and Dental Research Trust (P&G) £1900, Oral and Dental Research Trust (3M ESPE) £1500.


Undergraduate Teaching

I currently lead the undergraduate orthodontic course, which combines lectures, seminars and practical courses to give undergraduates an understanding of the role of the general dental practitioner in supporting and referring orthodontic patients.  I contribute to other courses, including Histology, Embryology & Development and Child Dental Health.  

Postgraduate Teaching / Research Support

I deliver seminars to restorative and orthodontic masters level students and am involved in the supervision of research projects at masters and PhD level.
