I am a researcher currently pursuing a Sêr Cymru II Fellowship part-funded by the European Regional Development Fund through the Welsh Government working in the field of Nanotechnology specialising in the characterisation and control of the electrical and structural properties of nanowires and nanocontacts.

I predominantly use techniques such as multi-probe STM, AFM, XPS, SEM, TEM and aberration-corrected STEM to correlate the structural and chemical properties of 1-dimensional nanostructures to their electrical transport behaviour.

I have other research projects such as surface modification and functionalisation of nanoparticles, pathogenic spore interaction with insects, lifetime and wear of human prostheses and chemical modification and growth of oxide nanostructures.
