I am a grad student.
I am taking a course wherein we were asked to do a group project. I asked around a few people but people seemed "paired up". I found a group of two people willing to take me in.
First few days it was fine. Then the presentation came by, one member vanished and the other one "deleted" the slides he was supposed to discuss, made up an excuse, and in the end I ended up giving the presentation. The person was also controlling the slides while I was talking and at a point pretended that he couldn't move the cursor as the system hung up. We had to abort the presentation then. Moments later, another person came to help us out and as it turns out the system was perfectly fine. The guy only did that to sabotage my presentation. Why would he do that? Also the person who actually didn't show up got to the presentation last moment and started talking about it as if they knew everything about it(they made some wrong facts).
Its only later I found out that the aforementioned person (ppt killer ) is actually a really dishonest person (fabricated data due to which was kicked out of his phD program, got a masters instead and will be allowed to graduate sooner) and the other person is chums with him. Now we're working on something only I'm knowledgable about because of my previous work in the field (they are completely relying on my expertise, even the project title and content was chosen by me). This weekend we were supposed to have a meeting, just before the meeting I sent a paper which would form the crux of the whole project. After making it to the place, no one showed up and they suddenly made up excuses of not being able to make it.
I feel cheated, like they're only using me for my knowledge and excluding me out of all the real discussions and work for the project.
Should I ask the professor to change my group? As its still early on. Is this the right thing to do? Crossing those two seems bad, they look like the department "shitmouths" to me, always engaged in the latest gossip. What should I say to the prof, please give me some advice.
