I am a PhD student in the Astronomy and Astrophysics group at the University of Warwick. My supervisors are Richard West and Don Pollacco.

M dwarf exoplanet survey

I am conducting a survey targeting M dwarf stars using NITES, our 0.4m telescope in La Palma. This is searching for exoplanets using the transit method, where periodic dips in the amount of light can reveal an exoplanet along with its radius and period. M dwarfs are an attractive target as their small size means Earth sized planets produce larger dips than they would around the Sun, and their faintness means their habitable zones are much closer to the star. The result is detecting Earth sized planets in the habitable zone is much easier than around Sun-like stars.

I am also responsible for scheduling follow up observations for transit confirmation using NITES.


I am part of the Next Generation Transit Survey (NGTS) consortium, which is conducting a wide field survey looking for transiting exoplanets in the southern sky from Paranal Observatory in Chile. I conducted a project investigating the photometry of saturated stars. These stars are the brightest in the survey and offer excellent opportunities for follow up investigation to find out more about their planets.

I was a planetarium co-ordinator from 2017-2019, organising visits to local schools and youth groups and running workshops for larger events on campus. More information about the planetarium can be found here.

Popular Astronomy Magazine

I am a regular news section writer for Popular Astronomy, the magazine for the Society for Popular Astronomy, with articles on exoplanets (‘TRAPPIST-1 planet masses suggest water rich worlds’), new instruments (‘Habitable Zone planet finder: the most precise hunter for rocky planets in the near-infrared’), planetary formation (‘ALMA reveals twin baby stars fed by a cosmic pretzel’), planetary exploration (‘Taking the plunge: Cassini dives between Saturn and its rings’) and extragalactic astronomy (‘Supermassive Black Holes Merge in Obscured Galaxies’).


I am also part of the Astrobites organisation, which posts daily summaries of recent astronomical research articles aimed at undergraduate physical sciences students. Links to my articles can be found below.
