I'm an undergraduate involved in a research project. My advisor is a faculty member who has requested that I walk him and our postdoc collaborator through a paper that is relevant to our project; it's a 24-page in-depth journal article. I made an attempt at walking them through a shorter article last week, but the PI said that I needed to work on better telling the story behind the paper instead of summarizing it. Have you had to develop the skill of walking your superiors through research that you didn't conduct? Can you offer advice on preparing this talk? I should note that I get nervous when speaking, so my memory isn't my best friend when I'm talking. Thank you for your tips.
