Head of Funds vs Head of Portfolio Management

Hi guys, I'm currently an intern looking to swap teams after my internship and I'm going to talk to two directors, one who is the Head of Funds and the other who is the Head of Portfolio Management. The problem is, that I have no idea how their roles are actually different and I'm hoping someone can explain.

I'm interested in working in an area closely related to investing and the people who work under the Head of Funds are in internal investment product and the ones under the Head of Portfolio Management are portfolio managers. I'm not sure which one would be best for me to try to get into?

Thanks
