Research Interests

Our research is focused on the development of integrative structural methods, combining experimental data with bioinformatics and modelling techniques, to characterise macromolecular machines. Structural models are further analysed to understand their function and design new experiments. The group is particularly interested in using data from cryoEM, cryoET, and Mass Spectrometry. In collaboration with experimentalists, specific systems we currently study include HSV-1 and HCMV sub-complexes, ligand-gated ion channels, and microtubule complexes.
