So the abstract I submitted to the MRS Fall Meeting seems to have gotten upgraded to an invited talk, which made me super excited. But in talking to my PI, it seems one of the session chairs had contacted him, and upgraded it under the assumption he would be speaking (which he never mentioned to me before the official acceptance notices came out). However, I wrote the abstract, everything we're proposing to present in the abstract is my work, and frankly, I give a pretty good presentation. We're the only authors on it. Also, if I'm not presenting, I can't get funding to go.
So instead of looking like I get to give a really awesome talk on all the cool shit I do at a meeting I've never gotten to go to, my advisor is going to give it instead, and I'm not even going to get to go. Having sat through his presentations on my data before, this really worries me, because he gets things wrongs, or claims things are definitive that are really not decisive at all. I was really excited about this, so it's a hell of downer to end my week on.
Is it usual for students to be upset when PIs give talks on their behalf, or am I being weirdly possessive about this?
