I am a first year PhD researcher working with the white dwarfs and transients research group. My supervisor is Deanne Coppejans. I study AM CVn stars (a sub-class of binary white dwarf stars) in the radio spectrum using data from the VLA. I completed my MSci at the University of Birmingham with my final year dissertation on machine learning applications for radio astronomy, with a focus on classification of radio objects from MeerKAT. I also work with the GOTO and ePESSTO+ collaborations for follow-up and data analysis on transients.

Past Research

  • Using data from the MeerKAT galactic plane survey and the VLA FIRST survey, I constructed a deep learning model which identified and classified different radio objects within the MeerKAT galactic plane survey. This was done in conjunction with a GAN (generative adversarial network) to generate synthetic radio images from the MeerKAT GPS for training the classification algorithm. This project was performed as a preparatory study for an automated classification algorithm to identify radio objects with the Square Kilometre Array (SKA) when it will be operational in the near future.
  • Due to inaccurate weather outputs from on-site weather stations at the SPECULOOS South Observatory, Paranal, Chile, resulting in a reduction in observation time, I constructed an algorithm which analyses the sky conditions in real-time from an on-site All-Sky camera. This provided accurate sky conditions with accuracies of over 90% which would result in an increase in observation time, thus aiding the detection of transits with longer durations.
  • During my third year of my BSc/MSci, I calculated habitable exoplanet occurrence rates around K dwarf stars, using a simulated set of stars from TRILEGAL. I applied this for the upcoming ESA PLATO mission, and contributed to the asteroseismology aspects of the project involving simulating oscillation curves of these stars too.
