To students

I am accepting new PhD students. I am also happy to chat to any PhD or undergraduate students interested in galactic archaelogy, statistics or machine learning.

To postdocs

If you are looking to apply for one of the fellowships (Rutherford, Royal Society or others) and are interested in doing it in Edinburgh and work in the general area of Galactic archaeology, please check this page, and feel free to contact me to help with the application process and sponsor your application.
