I have expertise in a wide range of biophysical techniques to characterise protein-protein and protein-ligand interactions to understand complex formation and aid assay development.
I am also interested in the mechanism of the abundant, cytosolic heat shock protein 90 (Hsp90), a molecular chaperone whose activity is crucial for the maintenance of the transformed state. Hsp90 faciliatates the activation and assembly of oncogenic proteins involved in key regulatory pathways in cancer including kinases, polymerases and transcription factors. Consequently, Hsp90 is now regarded as an important therapeutic target. There are several Hsp90 directed anti-tumour drugs in development and clinical trials.
