Is the expression "Deputy Head of Research" correct?

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.
