An active field of research is the production preferentially orientated defects in diamond. Simultaneous control over defect orientation is especially beneficial in the engineering of many NV-based diamond devices, such as quantum information applications and improving the signal of sensors. The aim of my PhD research is to be able to engineer the orientation of useful defects in diamond and direct their diffusion. This is being explored through the application of uniaxial stress to diamonds as they undergo the annealing process. Initially work is being focused on the split self-interstitial, with the application of stress parallel to . This will allow the activation energy to be determined and will enable its migration mechanism to be better understood. Understanding of the split self-interstitial will provide excellent groundwork for an investigation of the technologically important nitrogen-vacancy (NV) defect.

It was the undertaking of this final year research project that changed my mind and encouraged me to pursue a PhD. I enjoyed the research and working with the group so much that I decided to continue working in scientific research.
I love studying science and am really keen on getting others excited about it too. I've been a part of a number of outreach events organised by both our research group and the Warwick physics department.
Feb 2020: Warwick Science Gala
Demonstrations of our research group’s field to school age children and their parents. This included photoluminescence of differently grown diamond to show the different colours emitted. We also had diamond bonding kits and the ice melting experiment.
Nov 2019: Warwick Christmas Lecture
Interactive science demonstrations for the public before the lecture began. Centred around demonstrating the thermal conductive properties of diamond using ice. (See photo)
