I'm married with a child and consequently not able to move to the universities which have the supervisors I'd really like to work with. How important is it to be based near the university you are doing your research? Is it feasible to apply somewhere, but only visit for fortnightly meetings? Or, how likely is it that I could be based at my local university (where I'm about to start teaching) but have a supervisor from a different university? What are the pros and cons of being some distance away?
