Our internationally-recognized research in viral and structural proteomics, and bioinformatics, uses cutting edge mass spectrometry technologies that we both develop and apply.
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.
