I have an advisor who interferes too much with my research. When I am in the lab he always comes and sits near me telling me exactly what to do even the tiniest details, and most of the time he is just doing the design himself (Actually holding the mouse and doing the design) and I am just sitting and looking at him. The only tasks I am asked to do on my own are the simplest tasks that require no brain abilities at all.
Once, he got angry because I was trying some design I found in a book and he got angry and told that I am wasting time and I should do only what he tells me to do. I come to work at weekends only to find him waiting for me, and doing the same all over again. He calls me at weekends and during work days when I am not in the lab to come and work just to give himself an excuse in front of other professors to sit on my station and design.
I have to submit my thesis very soon, and when he sees me writing it he tells me that I am wasting time and I should do the stuff he asked me to do. I told him the I have an external examiner which have to see a draft very soon when I defend my thesis, and he said "Yes and I am in your committee and you have to make me happy".
Seriously, I just want him to back off! I feel very offended by this treatment and that I am just a "trained monkey" who does only what he asked to do.
What words can I use to tell him that he should give me my space and that I want to do my research on my own ??
