Overview

I received my BSc (Hons) in Physics from the University of Bristol in 2017, and my MSc in Physics from Cardiff University in 2018. As of 2020, I am an Associate Fellow of the Higher Education Academy (AFHEA).


I am currently a PhD student (2018-2022) studying non-linear optical fabrication and characterisation techniques and how these can be applied to nanostructured magnetic and artificial biological systems, under the supervision of Dr. Sam Ladak and Prof. Wolfgang Langbein. 


I tutor and demonstrate on MSc level modules PXT101/201, PXT102/202 and PXT103 with Dr. Richard Lewis and Prof. Paul Roche. 


Research

Research interests

My work currently focuses on: 



  • Nanostructured 3D magnetic systems including nanowires, nanotubes and more complex 3D geometries 

  • Non-linear optical techniques for the fabrication and characterisation of polymers and magnetic systems 

  • Electrochemistry and its application to magnetic nanostrucutre fabrication 

  • Micro-magnetic simulations 


Specifically I use the following techniques in my research:



  • UV lithography 

  • Two-photon lithography

  • Magneto-optical Kerr effect (MOKE) magnetometry

  • Electrochemical and electroless deposition 

  • Scanning electron microscopy (SEM)

  • Quantitative differential interference contrast (qDIC) imaging 

  • Finite difference micro-magnetic modelling (e.g MuMax)
