Selected Projects

  • Osseointegration around titanium implants and diabetic bone healing.
  • Influence of surface modification of titanium on progenitor bone cell behaviour during osseointegration.
  • Adult stem / progenitor cells from bone marrow and dental pulp and role of the extracellular matrix in stem cell biology and mineralised tissue repair.
  • Influence of bacterial pathogens (LPS) on altered bone cell activity, protein synthesis and remodelling of the extracellular matrix during inflammatory periodontal disease.
  • Matrix metabolites and cytokine profiles as biomarkers in gingival crevicular fluid and their development as chair-side diagnostic assays of active periodontal disease.
  • An ex vivo mandible culture model to study inflammatory bone disease and bone regeneration.
  • The role of the extracellular matrix in growth factor presentation during mineralised tissue repair.
  • Ex vivo modelling of antimicrobial measures in pulpal disease.
  • Dentinal matrix components in gingival crevicular fluid as biomarkers of root resorption.
  • Host-microbial interactions and cellular responses associated with Streptococcus milleri infections.
  • Use of recombinant and native proteins in the evaluation of the functional roles of small leucine rich proteoglycans and dentine phosphoproteins in bone and dentine.
  • Influence of fluoride on protein on altered bone cell activity, protein synthesis and remodelling of the extracellular matrix.
