Research Interests

We are interested in solving questions about the biology underlying health and disease by studying molecular processes and pathways. To do this we use a range of techniques including mass spectrometry, biochemistry, molecular biology and informatics, to study protein function, proteome composition and organisation.

The Proteomic mass spectrometry team complements the research programmes of the Sanger Institute to further understanding of the relationship between the genome and the proteome (expressed protein complement). Through our research and collaborations we explore protein-protein interactions, cell signalling and protein expression in a range of human, pathogen and model organisms.

Our research portfolio encompasses all levels of proteome complexity: from whole organism characterisation to subcellular organelles, from protein complexes to post-translation modifications.
