Research interests
My interest lies in cancer and ageing research. By investigating the molecular details of tumour-suppressor p16 oxidation, my aim is to understand the role of this novel transition in cancer. I am particularly interested in determining the progression of p16 into an amyloid state in different cancer cell lines. I specialise in fluorescence microscopy and cell culture techniques but also explore biophysical methods using recombinant p16 protein.
