I'm an incoming freshman interested in research, and have a meeting next week with a PI whose lab I want to work in. According to the email, i'm going to be sitting in on a lab meeting and then talking with the PI. I've already read several of the PI's abstracts and tried to (confusingly) read some papers, but I don't know what else I can do to prepare. I have a general idea of what the lab focuses on, but am I expected to be super knowledgeable about everything? As for the lab meeting- what's the proper etiquette for how I should act? I don't know if I should sit quietly and listen/take notes, or be more involved? Any advice is much appreciated to calm my nerves!!
