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 for a list of opportunities, and feel free to contact me to help with the application process and sponsor your application. Keep in mind that many of the applications have an internal (within Edinburgh) selection process, so please contact me in advance. On top of fellowships listed there are also Chancellor fellowship.Featured recent papers
