In my university department there is a professor who holds the position of Head of the department, and then there are also several Deputy Heads, who are in charge of different management areas —more precisely: Research, Teaching and Infrastructure. Notice that, in our case, the Head and the Deputy Heads are not necessarily 'senior professors' or 'full professors'; they can be also (young) 'associate professors'. They are in fact elected by popular vote within the teachers belonging to that department.
My question is just this: What is the right way to refer to the Deputy Head who is in charge for the Research matters of the department?
Research Deputy Head?
Deputy Head for Research?
Deputy Head of Research?
Actually, I am not sure whether the term 'Deputy Head' is right or not, in this context.
I would appreciate your feedback on this terminology question.
