About Me

I completed a Master of Physics (MPhys) degree at the University of York in 2018.

My PhD centred on Skyrmionic materials and exploring new materials which may exhibit this behaviour. I worked under the supervision of Prof. Geetha Balakrishnan.

I studied some intercalated transition metal dichalcogenides that form in a space group that has potential for skyrmionic behaviour, and some of which have been shown to host interesting magnetic phenomenon such as the chiral soliton lattice.
