  • Yes, it is true that I poorly understand what I am doing, but I am a molecular biologist and I don't have degree in bioinformatics/statistics/or any computer related field. I don't want to describe here my situation with my supervisor, I have now two ways out from my situation - give up on my PhD or do everything I can do to finish.My supervisor doesn't want to collaborate with anyone, he says that "this is easy". Instead of getting to the end of my PhD I find myself fighting with my supervisor and seeking for help on forum. All I dream of is to finish and find a job within a group doing 'real' metagenomics. But, without any publications I don't have chance to obtain that.
