It it were a case where abstract inheritance would work, I would agree. Unfortunately, the Researcher model can't be abstract (because it has its own relations with Publications).

If I use multi-table inheritance, that solves part of the problem. However I don't know how well it would work if I have a Researcher, who at some point needs to be a ResearchStudent and maybe later becomes ResearchStaff.
