My research interests encompass the structure-function studies of proteins and peptides with diagnostic or therapeutic potential . Early graduate and post-graduate research include the structure [2-4], immunochemistry , paleobiochemistry , and clinical studies   of a small post-translationally modified protein osteocalcin used as a diagnostic in bone disorders.
Post-doctoral investigations involve Resonance Raman Spectroscopy  and electrochemical techniques  successfully applied to selected metalloproteins, and molecular modelling of post-translationally modified protein derived from a pathogen . My interest in the structure-function relationships of proteins continues today with an emphasis on characterising proteins, peptides, and biomimetic peptides for therapeutic development for oral health. The research includes the purification , characterisation [13, 14] and structural studies  of a highly post-translationally modified protein phosphophoryn and the synthesis  and structural studies of a phosphophoryn derived biomimetic peptide  with potential in dentine repair.
The multi-disciplinary research describing the purification, characterisation [19, 20], structural studies [21-24], and molecular modelling [25-27] of casein phosphopeptides (CPP) has demonstrated that the non-toxic and biocompatible CPP self-assemble and encapsulate the calcium and phosphate mineral in the form of amorphous calcium phosphate (ACP) thus forming CPP-ACP nanocomplexes. The biomedical application is the demonstrated repair of tooth surfaces at early stages of tooth decay. This research has contributed to the scientific evidence for the currently commerciallized CPP-ACP ingredient found in sugar-free gum (Trident XtraCare with Recaldent), professional tooth crème (GC's Tooth Mousse, MI Paste, and MI Paste Plus), and dairy milk (Meiji Milk de Recaldent). (http://en.wikipedia.org/wiki/Recaldent). The long-term goal is to improve the design and efficacy of non-toxic self-assembling, biocompatible, delivery vehicles for mineral ions with current applications in the biomedical, health and pharmaceutical industry.
My research interests also include the diagnostic and therapeutic potential of saliva. This is highlighted by the research describing the diagnostic potential of salivary pH for clinical applications [31, 32], evolution of salivary proteins , the salivary peptidome , and the recent emergence of saliva-derived peptide therapeutics.
Our tradition of sourcing bioactive peptides from natural products led to the screening of casein peptides for inhibitory activity against the virulent outer membrane protease gingipains of the oral pathogen P. gingivalis. These studies enabled the discovery of inhibitory peptides derived from milk caseins [[34, 35] & patent PCT/AU/2010/000760].
I am also interested in the evolutionary relationships and different inhibitory mechanisms of known cysteine protease inhibitors and its relationship to modern chemotherapeutic design for the treatment of infectious diseases . My interest in molecular evolution of proteins and the effect on structure-function relationships continues with the current investigation of the use of the propeptide as an effective inhibitor of the oral pathogen P. gingivalis gingipains [provisional patent 2010/902955].
