Overview

I am PhD research student based in Cardiff University's school of Physics and Astronomy, specialising in interacting supernovae. I have studied several types of exotic transients, ranging from Type IIn to Type Icn SNe, through optical and near-infrared bands for spectroscopy and from near-UV to near-IR for photometry. My thesis currently is looking at the host environments of Type IIn and Type Ibn and if there are any correlations between host environmental properties, both global and local, and the type of SN.

My first published paper covered a rare transitional transient, SN 2024abvb, that was unique in its separation from its host, being one of the furthest at ~21.5 Kpc. I presented the spectroscopic and photometric data from this supernova and considered the different possible progenitor scenarios.

I previously completed a Master's (by Research) at University of Hertfordshire, studying the kinematics of subdwarf B stars.
