Background

Activities

My primary research interests include designing and characterizing novel glasses for use as medical devices. Principal analytical techniques for glass design include X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS) and Raman Spectroscopy. Further interests include quantifying ion release from bioactive glasses/materials and their effect on common skin microflorasuch as bacteria (E. coli, S. epidermidis, S. aureus, P. aeruginosa) and yeast (candida albicans) responsible for infection. My research interests also include cytotoxicity testing of biomaterials on mammalian (Mouse L929 Fibroblasts) cells, with the intention to commence testing on both bone and cancer cell lines in the near future. My current research projects include:

• Fabrication of Glass/Ceramic Cell Scaffolds for increased bioactivity.

• Glass Coatings to increase the antimicrobial response and their subsequent diffusion through soluble and stable Hydrogels/Gels for applications in wound healing.

• Bone Cements based on Glass Polyalkenoate Cement chemistry for load bearing applications.

• Anti-cancerous Bone Cements and Degradable Bioactive Glasses.
