I am a fixed-term lecturer in astrophysics. I recently completed my PhD here at the University of Sheffield and I am proud to call Sheffield my home. My research focuses on astronomical instrumentation and time-resolved astrophysics, including compact binary stars, transiting exoplanets, and transient events. I have helped commission the high-speed imaging camera ULTRASPEC on the Thai National Telescope, and the fully robotic pt5m telescope on La Palma.

I have studied eclipsing cataclysmic variables (CVs), searching for new eclipsing systems and characterising those systems which are already known. CVs play an important role in binary stellar evolution, and may provide a pathway for the creation of Type Ia supernovae, which are used as a standard candle to measure the expansion of the Universe.
I have conducted extensive optical follow-up observations of a wide range of transient events, including dwarf nova outbursts, supernovae, gravitational lensing events, and gamma-ray bursts. I collaborate with the Gaia Science Alerts team, who find transient events in the data collected by the astrometric satellite Gaia. I have also searched for optical counterparts to the recently discovered fast radio bursts, whose origins are still unknown.
