Background

I graduated from the University of Glasgow with a first class Masters in Physics with Astrophysics. During the last couple of years of my undergraduate degree I carried out a number of projects in materials and condensed matter physics using electron microscopy, it was during this time I gained an appreciation of the impact that material properties had on their application and how they could be tailored to meet different criteria. I applied for the DST CDT as the interdisciplinary nature of the course will provide me with a good base of knowledge and experience from which to progress into my PhD. My PhD will involve using electron microscopy to characterise defects and dislocations in both natural and synthetic diamond. It will take place at the University of Warwick under the supervision of Dr Richard Beanland.

PhD Title: Electron Microscopy of Dislocations and Vacancy Clusters in Diamond

PhD Supervisor: Dr. Richard Beanland

Institution: University of Warwick

Interests

My research looks to use a variety of electron microscopy techniques to image, and characterise the properties, of extended defects and dislocations in natural diamond. The purpose of the research is to investigate any changes that occur to the extended defects during the heat treatment of brown diamonds, which then turn colourless. Changes to the extended defect structure may provide a new pathway for the detection of heat treated stones.

Some of the techniques being utilised are: Scanning Transmission Electron Microscopy (Bright Field, Annular Dark Field and High Angle Annular Dark Field), TEM, Electron Energy Loss Spectroscopy (EELS), Cathodoluminescence (CL) and Focussed Ion Beam (FIB; for sample preparation).

Teaching

I am currently a demonstrator for the 2nd year Physics undergraduate labs.

Conferences

The 69th Diamond Conference 2018 (Poster) - "Electron Microscopy of Dislocations in Natural type IIa diamonds".
