ok like every other curious permed i wanted to know what research is like (or put it down in my application)......either way, I deccided to join a lab past summer. The supervisor interviewed me, liked me and so I joined the lab as a summer student. He did have any extra funding for the projects and so I worked as a suumer student basically helping out the rad students in the lab, and learning various experimental procedures alongside. However, I started liking it and opted to do my honors thesis in the same lab (4th year research based course). Rite from the beginning of the summer, there is this one grad student who is very very hostile towards me. The lab is prety smalll since my PI is retiring soon. There are 3 ppl in the lab: me and 2 grad students. I first thought that maybe I am a new addition and so he is behaving like that. But no. He talks rudely and shows off/ bosses around with every single person. But I have a feeling he has a special grudge against me since he was the one who talked about the project with my PI, and maybe he wanted to work on the project. Howver, he is really rough on me ever since I started. He keeps saying things like "I think this lab work is too tough for a 4th yr" "why dont u start thinking (when i make a mistake)" Recently, I found out he told on me. My PI talked to me about i need to be mature as a 4th yr and start working blah blah. I am a 4th yr and put in all the time that a typical student does and have produced data that a typical 4th yr does (I talked to other students in the program about their progress). I really dont know how to tackle this problem. I feel like he is on my face everytime evn if it isnt my fault. For any experiment the other grad student does a mistake, they blame it on me saying I have contaminated the sampl or they used my reagent which killed their cells. I cant beleive my PI is following them (I cant blame him as he is away most of the tim and has to rely on their words). Anyways I am hurt deeply and want to find a solution to this until April when I'm graduating. Any advice ppeople. Apologise for my rant.
