Broadly speaking, I am interested in how we can translate condensed matter phenomena into the realm of polaritonics. Recently, there has been intense effort to emulate Dirac quasiparticles in photonics by mimicking the underlying honeycomb symmetry of graphene. However, since their existence is tied to the lattice structure, it is notoriously difficult to manipulate their properties, hindering their potential for practical implementation in novel photonic devices.
In recent work published in Nature Communications, we showed that this drawback can be overcome in the realm of metamaterials. We predicted that elementary honeycomb metasurfaces could support both type-I and type-II massless Dirac polaritons. Crucially, due to the mixed light-matter character of the Dirac polaritons, one can manipulate the fundamental properties of the Dirac polaritons by simply modifying the surrounding photonic environment.
In 2015, I graduated from the University of Exeter with a 1st class degree in Physics, during which I was awarded two scholarships for academic excellence and received the Bertie Black Prize for the most outstanding academic performance in the College of Engineering, Mathematics and Physical Sciences (CEMPS).
Having grown up in Cornwall, rugby became a huge passion of mine where I represented Cornwall and Devon counties at under 15s, 16s, and 18s age-group levels. Whilst always fascinated by science and mathematics my real passion for physics developed during my A-levels where I achieved four A*'s in physics, mathematics, further mathematics, and biology.
