There is another research group at another university in my town. They asked me to join one of their monthly brown bag meetings and to serve as a discussant. They have invited an external speaker and he will present something that is related to my own research.
I received the presentation slides in advance and I have read two related papers of the speaker to prepare. Although I do have some questions and points to discuss, I am not exactly sure how to go about this. I have never done this before and I have only once witnessed such a thing at a conference but thought the discussant there wasn't a good example. So I was hoping for some general advice and experiences. Some questions are:
- Should I prepare some slides myself?
- How long is this kind of discussion usually?
- Should I try to engage the audience or is it more of a one-on-one between me and the presenter?
