The coordinator needs to be so conversant with her topic that she or he can instantly change gears so as to better address the specific concerns of each successive team leader in turn.

Guys like that are worth their weight in Uranium. The lecturer above, Doctor Segre, is another such person. Boy, howdy, does she know her topic!
