I joined a PhD program in Germany 6 months ago. I have two supervisors here - one is a clinician and the other is from natural sciences background. I am really unhappy with the way I am being guided because really there is no guidance. The guy from the natural sciences background is my immediate supervisor. I have never seen him read any scientific papers. He also almost never participates in any scientific talks or conferences and even if he does his scientific work and presentation skills are sub-par. He never asks any scientific questions. The only inputs that I have received from him so far are regarding font size and margins.
Whenever I go to him with an idea, he says, 'Bravo! I was waiting for you to come up with this. I am really happy with your performance. Keep it up!' Initially, I thought that I am really a bright student but over time I realized that he says this for every idea of mine. I also tested him with absolutely rubbish ideas but his reaction remained the same.
Unfortunately, he has also hired other staff in the lab just as incompetent as him. All they want to do is finish their working hours and go home. Never have I received any scientific input from any of the post-docs or other lab members.
Now when I see presentations of other students, I get really worried because they are light years ahead of me. After asking them about how they manage to do such stellar work, they tell me that supervisor guides them to do so and also they also have lots of support from other members of the lab. As for improving their presentations, they often give mock seminars to their lab mates and receive a lot of valuable input from there.
Now, I do not want to be spoon-fed but nevertheless I need some guidance. I need someone to tell me if my line of thinking is right or wrong. I need someone who will point out flaws in my techniques. Neither my supervisor nor my lab mates can provide me this support. I got even more worried recently when a professor from another department clearly told me that I should continue in that lab only if my aim is to get a C grade PhD.
The thing is that I cannot change my current lab because I have already changed my lab once. The only way for me to get out of this mess is to make this work. Can someone suggest me on how to do good PhD given the above-mentioned circumstances? Thanks in advance.
