I work on wide-field time-domain and astrometric surveys, exoplanet transit detection, and near-infrared stellar astrometry. I build efficient, scalable software for analysing massive astronomical datasets — from individual light curves to catalogues of a billion stars.
My work spans wide-field time-domain and astrometric surveys, exoplanet transit detection, stellar occultations, and Galactic structure. I have a particular interest in low-mass stars and brown dwarfs — especially thick disk, halo, and benchmark examples — and in completing the census of the solar neighbourhood.
I enjoy the challenges of working with and analysing massive datasets, and writing efficient, scalable code. My current work at the Institute of Astronomy, Cambridge, focuses on GPU-accelerated transit detection for ESA's PLATO mission and near-infrared astrometry with VIRAC.
Development of a CUDA GPU-based transit detection pipeline incorporated into the ESA PLATO Exoplanet Analysis System. CETRA implements an optimised Box Least-Squares approach with adaptive frequency grids and parallelised execution, designed to operate at survey scale across the full PLATO photometric dataset. Work also includes GPU-accelerated transit light curve modelling and modelling of ring systems around exoplanets.
Production of a world-leading catalogue of stellar proper motions in the near-infrared Milky Way, derived from 14 terapixels of VISTA/VVV imaging. The pipeline processes over 100 billion detected objects, cleans the catalogue, and produces photometric and astrometric time series for over one billion stars. Proper motions are derived via robust regression and used to study Galactic structure, identify thick-disk and halo members, and mine for periodic variables using supervised machine learning.
Bayesian analysis of light curves from stellar occultations, with a focus on irregularly shaped objects in the outer solar system. Probabilistic shape modelling to constrain the physical properties of occulting bodies from high-cadence photometric observations.
