My interest in Physics and Mathematics stems from a deep curiosity about the world that we live in and how we can better understand it to solve problems and create solutions. This interest led me to studying a Masters in Physics at the University of Oxford in which I specialised in Astrophysics and Condensed Matter Physics. In my final year I worked in the area of superconductivity and my Master thesis was entitled: "Pulse field magnetisation of bulk high temperature superconductors (GdBCO) with a variety of sample and split coil geometries."


In 2018 I started studying for a PhD at the University of Exeter in the area of metamaterials. A metamaterial is a material that is engineered to have novel properties that are not usually found in nature. This is done by fabricating structures on the same scale as the wavelength of the phenomenon they are design to influence. I am specially looking at materials that influence light which means fabricating devices at the nanometer scale. My PhD title is "All dielectric phase-change metamaterial-based holography". My aim is to realise dynamic 3D holograms using tuneable metasurfaces.


I have a passion for sharing my love for Physics and Mathematics and have been an educator for three years teaching in schools in London and Exeter. My other interests include sustainable building techniques focused on straw bale building and passive house design, long distance cycling and climbing!
