Currently, I am in the third year of my PhD in theoretical physics in the EPSRC Centre for Doctoral Training in Metamaterials where I work with Dr. Eros Mariani & Prof. Bill Barnes.

Broadly speaking, I am interested in how we can manipulate the properties of light through interaction with matter. In particular, we investigate new, emergent physics in the simple crystalline metasurfaces that arises due to intricate non-local effects.  Recently, we have developed an analytical theory of the polaritons supported by elementary honeycomb metasurfaces. Here, we predict the emergence of a new kind of type-II Dirac point that arises from a non-trivial winding in the light-matter interactions and exists simultaneously with the conventional type-I counterparts. As a result of this unique physical origin, one has unparalleled tunabilty of the emergent Dirac polaritons by simply modifying the surrounding photonic environment rather than the lattice structure.

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.
