Current Research

I am a Research Fellow based at the University of Warwick, supported by a Royal Society Innovation Award. My research involves the application of boron doped diamond (BDD) for the development of sensors for extreme environments. In particular, I am working towards commercialisation of the pH sensor I invented during my PhD research. The boron doped diamond pH sensor, other than being the hardest material known to man, offers many other advantages over the commercially available glass pH probe, including resistance to fouling and the fact it does not suffer from alkali errors.

Being formally trained as an analytical scientist I am also heavily involved in the analytical community. I am an appointed member of the Royal Society of Chemistry (RSC) Analytical Division, and am a committee member of the Analytical Science Network. I am also publicity officer for the RSC Analytical Methods Committee and am an RSC Electrochemistry Group Committee member.

In the Past

PhD

I studied for my PhD at the University of Warwick as a member of Warwick Electrochemisty and Interfaces Group under the supervision of Professors Julie Macpherson and Mark Newton.

My research involved the 'Development of Diamond-based Electrochemical Sensors', initially being involved in the development and implementation of the newly patented technique Electrochemical X-ray Fluorescence (EC-XRF) for the detection and quantitation of heavy metals. My work progressed into developing a BDD pH sensor as well as exploring fundamental ways to probe sp2 carbon content in boron doped diamond.

MSc
I studied for the AS:MIT (Analytical Science: Methods and Intrumental techniques) MSc degree at the University of Warwick, which provided me with the opportunity to further my knowledge of analytical techniques and regularly engage in laboratory-based work. I was involved in a 6-month research project in collaboration with AstraZeneca:

 

Development of Diamond Based Electrochemical Sensors and Combined Spectroscopy Sensors for the Sensitive Detection of Analytes in Pharmaceutical Manufacturing Processes

Supervisors: Prof. Julie V. Macpherson and Drs. Andy Poulson, Andy Ray & Tony Bristow


I was also involved in a group research project to investigate culinary spices. This required researching analytical tests used in the food industry and taking them from methods to implementation within a short timescale. ISO standards were used as well as adapting methods from research papers. HPLC, ATR-FTIR, UV-Vis and ICP-MS were among the analytical methods used.

BSc

Previously, I studied my Bachelors's degree (BSc) at Nottingham Trent University in Forensic Science. My undergraduate project involved the analysis of Iron Age bones from Finn Cop Hillfort in Derbyshire for heavy metals, including Pb, Sr, Zn and Mn using ICP-OES. Conclusions about the daily lives of the Fin Cop individuals, such as dietary habits, could be drawn, with results validated against standard reference material.

Outreach

I am a STEM embassador and am always up for doing outreach activities. I have been involved in activities varying in scale from school visits to project managing an exhibition stand promoting diamond science at the Royal Society Summer Science Exhibition 2016, with over 12000 of the general public visiting us in a week.
"Diamond: more than just a gemstone" Royal Society Summer Exhibition

Chemistry at Work, ThinkTank Museum, Birmingham - giving school children an insight into chemistry at work
