Academic Background

MSc Molecular Analytical Science (Distinction) - University of Warwick 2016

MSci Chemistry (First Class Hons) - University of Birmingham 2015

Awarded the Allen Murray Centenary Scholarship from 2012/13 to 2014/15.


PhD Project

I am currently in the third year of my PhD in Analytical Science. My project, titled Petroleomics: Crude and Heavy Fuel Oil Fingerprinting and Asphaltenes, builds on the MSc Mini Project and is supervised by Dr Mark Barrow (Department of Chemistry) and Dr David Growney (Lubrizol Ltd). I attend a biannual University Contacts Meeting (UCM) at Lubrizol Limited, where I present the project as it progresses.

Previous Work

MSc Mini Project 1: Petroleomics - Crude Oil Fingerprinting and Asphaltenes

Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) was used for ultrahigh resolution characterization of petroleum samples. The PhD aims to build upon the success of this project and investigate the key components of selected petroleum samples, with respect to learning more about bulk properties.

MSc Mini Project 2: Investigating Autoxidation Mechanisms by EPR Spectroscopy

Radical formation was monitored in active pharmaceutical ingredients (APIs) and model compounds to provide an indication of their susceptibility to autoxidation under a range of experimental conditions. Little correlation was found between radical concentration and computationally determined bond dissociation energy values, highlighting the need to consider other degradation pathways for systematic risk assessment of API stability.

MSci Final Year Project: NMR Studies of Reverse Micelles

Reverse micelles were characterised using Pulsed Gradient Stimulated Echo (PGSTE) measurements as well as Multiple Quantum Filtered Magic Angle (MQF-MA) experiments at the University of Nottingham. The size of reverse micelles was confirmed to increase with increasing water to surfactant ratio, while their shape was found to be unaffected by changes in temperature or solvent phase.


Other Interests

I am currently a Leader in Training at my local Guide Unit, helping to deliver a varied programme of activities and building confidence and leadership skills for girls and young women.
