Research interests

Our research interests focus on the study of protein interactions using cutting edge mass spectrometry and proteomics approaches that we both develop and apply.


Current research projects :

1. Viral proteomics using MALDI-MS for surveillance of the type, subtype and antigenicity of the influenza virus to monitor the evolution of the virus and identify the emergence of highly virulent new strains.

2. Application of Radical Probe Mass Spectrometry (RP-MS) to study protein interaction interfaces and the impact of oxidation on these interactions. Our research is focussed particularly on long lived tissue proteins.

3. Development and application of new computer algorithms (eg. COMPLX, PROXIMO and PRISM) and approaches to obtain information on the structure and interactions of proteins from mass spectra and to advance bioinformatics. Other algorithms to deconvolute ESI mass spectra (CRAM) and advance "shotgun" proteomics (ETISEQ) have also been written.


PhD research opportunities are available to qualified local and overseas students.
