Research interests

I am interested in planetary materials, particularly the composition of meteorites and Apollo samples.

My current research, funded by the Leverhulme Trust and supervised by Professor Ian Crawford, aims to study how the flux of galactic cosmic rays (GCRs) impacting the lunar surface has changed with time, and to relate this to the Solar System's past locations in the Galaxy.

Unlike the Earth, the Moon possesses an ancient surface with no atmosphere or magnetic field. Therefore the regolith contains records of GCRs which can be used to help with the reconstruction of the galactic environment throughout the history of the Solar System. This involves a detailed study of the abundances of cosmogenic nuclei which are produced through the interaction of GCRs with atoms in lunar materials and are therefore present in lunar meteorites and Apollo samples.

The ultimate aim of this project is to assess the value of the lunar geological record for galactic astronomy.
