I've just started a PhD. Currently I only have one person who is supervising me (the professor). So he is now both my supervisor and my promotor.
Now other (ex) PhD students are telling me that these roles should be filled by different people, to prevent mix of interests. But I don't have sufficient insight on what they are referring to.
Should I be worried? Should I talk to my department head to change the situation?
edit, let me clarify:
- With "promotor" I mean the main project supervisor, being a professor. He has the final responsibility.
- With "supervisor" I mean the daily supervisor, sometimes also called co-promotor. To my understanding this is often somebody else, for instance an associate professor or assistant professor.
