My research covers a number of application-driven themes centered around electrochemistry, materials science, and new characterization techniques.
(1) Understanding the link between the material properties and electrochemical properties of carbon-based materials
(2) Development of synthetic diamond electrochemical based sensors for a variety of different applications in healthcare and environmental monitoring (often in collaboration with industry).
(3) Metal electrodeposition: Production of novel nanostructures and understanding early stage nucleation and growth. For a recent talk on the subject see https://m.youtube.com/watch?v=SSlaxoyvHw4
(4) Understanding electrocatalyst activity and deactivation mechanisms of metal nanoparticles, important in energy conversion.
(5) Development of new analytical measurement techniques
The group uses a range of electrochemical techniques, but also works with scanned probe and scanning and transmission electron microscopy for high-resolution imaging of nanostructures. Fabrication of sensors and electrochemical cells using 3D printing, laser writing, and lithographic techniques.
I am significantly involved in the UK's first Collaborative Doctoral Training (CDT) Centre in Diamond Science and Technology (DST), I held a Royal Society Industry Fellowship with Element Six (2014-2018), aimed specifically at the development of BDD electrochemical sensors. I was awarded (2017) the Royal Society Innovation award for my work in this area.
