Centre for Misfolding Diseases

Research Associate

I currently work at the Centre for Misfolding Diseases at the University of Cambridge. The focus of my original research programme is to develop and apply new Physical methods at the interface with Chemistry and Biology to shed light on the molecular processes underlying the onset of neurodegenerative disorders and study functional biomaterials for biomedical applications.

In my research, I continuously push the boundaries of the methods of analysis of modern biology and physics for investigating complex and heterogeneous biological samples and biomaterials at the nanoscale. I have deep expertise in scanning probe microscopy, surface science, spectroscopy, data analysis, image processing and single particle characterisation.
