My research focuses on exoplanets, eclipsing binaries and variable stars, particularly those observed by the Kepler and K2 telescopes. I work on population statistics of circumbinary planets, as well as methods for detecting them in photometric surveys. My other interests include studying the habitability of known exoplanets, variability in planetary phase curves, and planet detection and characterisation using the Kepler, K2, WASP and future surveys.
Outside the area of planets, I have an interest in the extraction and utilisation of high-precision photometric data, as well as applying machine learning techniques to astrophysical problems. Recently this has included creating fast detection and classification tools for eclipsing binaries and variable stars in the K2 survey.
