A couple years ago I was applying for personal fellowships to return to the homecountry and work in a PI's lab in order to set up my own group within their bigger lab (which is how things usually go in the homecountry). I talked to a junior groupleader (JG) in this lab and we brainstormed about what I would write in my fellowship. I wrote the fellowship and asked JG for feedback because they had experience with said fellowship. I submitted the fellowship and it got rejected. Twice. Then I moved back to the homecountry and JG told me they were doing one of the experiments that I had proposed in my fellowship. And recently I saw that they had published the results. Aim 1 of my fellowship is done. But not by me. If this doesn't make you a disgruntledpostdoc, I don't know what does.
What is the worst academic backstabbing you have experienced?
