Our research aims to visualise the three-dimensional architecture of large macromolecular complexes that play critical roles in cancer biology using cryo-electron microscopy (cryo-EM). By integrating structural insights with molecular biology, cell biology, and biochemistry, we reveal how these complexes function and drive cancer-related pathways. Current efforts focus on two areas: chaperones that activate assemblies such as mTORC1—a key regulator of cell growth and metabolism—and the study of DNA repair and genome stability complexes, which safeguard genetic integrity and whose malfunction underlies tumour development. In collaboration with other groups, we also explore the mechanisms of microtubule nucleation that orchestrate mitotic spindle assembly during cell division, a process fundamental to both normal proliferation and oncogenesis. Our ultimate goal is to generate mechanistic knowledge and a deeper understanding of biological processes relevant to cancer biology.
