Main Research Areas: Mass Spectrometry, Proteomics, Protein Structure and Biology, Protein Bioinformatics, Computational Biology

Our internationally-recognized research develops and applies mass spectrometry technologies and associated computational approaches to advance our understanding of the role of proteins in disease pathogenesis. We have a particular interest in studying the influenza virus, its evolution and new ways to respond to the disease. The virus is responsible for some 1 in 1000 deaths of all humans who have ever lived and our work is aimed at arresting its impact. Current active areas of research include:

Current research projects :

1. Viral proteomics using MS for surveillance of the type, subtype and antigenicity of the influenza virus and other biopathogens to monitor their evolution 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 to assist our influenza studies (FluShuffle, FluResort, FluTyper, FluAlign, FluGest, MassTrees) and approaches to obtain information on the structure and interactions of proteins from mass spectra (eg. COMPLX, PROXIMO and PRISM). Other algorithms to deconvolute ESI mass spectra (CRAM) and advance 'shotgun' proteomics (ETISEQ) have also been written.
