I don’t normally post job vacancies on the blog, but this is an unusual one. For anyone who has not been scared off interdisciplinary study by Guy Halsall, the University of Leicester have the ultimate (funded) PhD opportunity on a project called Roots of the British, which brings together historians (such as Jo Storey), geneticists, archaeologists and linguists to look at migration 1000 BC-1000 AD. You will get training in history or archaeology or genetics as appropriate and they even give you desk space (which is more than KCL ever gave me). You might even be able to make a living subsequently, as Bryan Sykes has.
The deadline is 25th August, which unfortunately does not give you time to change your surname to a rarer one.
