Hi all, I have a friend who wants to get a PhD in Physics, and ultimately wants to be a tenured professor at a university or smaller college in the USA. He is considering going to graduate school in the UK or Canada. He wants to know if this will make it harder for him to find a tenure track position or postdoc once he is done with his PhD. He is currently looking at Cambridge, Imperial College, King's College in the UK, and University of Toronto, McGill, UBC, Waterloo in Canada. Does anyone know of any other very strong physics PhD programs in the UK or Canada (he strongly prefers a metropolitan area, ie a place like Toronto or London)? Thanks in advance!
