I'm almost at the end of my Ph.D., writing down the thesis and having the disputation.
Well, my Ph.D. took me about 5 years. My main background is Engineering, but I changed my research domain to Computer Science during my master study. So, my supervisor had a mindset at the beginning that I'm an engineer, but I can survive the Ph.D. project. The first year went fine, I published a paper. I did another in the second year, and I like my Ph.D. topic. During the first year, I noticed that she doesn't have any specific idea regarding how to proceed the Ph.D. work. I wasn't expecting her to instruct me in details but I was expecting some better abstract insight from her regarding my Ph.D. project.
Starting from then I tried to do my best using the literature and my own ideas. But I wasn't getting any feedback from her regarding my work, and how it looks in the general perspective of the field. I tried some top-tier conferences for which I got some rejections but at least I obtained some feedbacks regarding my work, that I was expecting to get from my supervisor in the first place.
Regarding reading my papers, sometimes she didn't have the time due to the closeness of the deadlines (which is a valid excuse), but even when she had the time, she was reading my paper with hesitations and biases. I was feeling a strong hatred in her destructive comments without providing hints and guides how to revise it. Even sometimes I felt being offended as she was criticizing my non-mathematical background and how my work does not feet to this field. Also, even if she was reading my work, she was so careless in doing it especially to find the important facts in the work which led to the rejection as all the reviewers noticed that easily!! Worst than that, she never dares to discuss why my work was rejection and how to revise it, or how to answer the reviewers wisely! For instance, I had a good chance at a top-tier conference but I failed the rebuttal phase while she just ignored my request to guide me through it.
During the 4th year, it was clear to me that I have a total ignorance from her, like if I'm not a part of her group anymore. She answers one out of every 5 emails from me after a second request! But I see her being different from others and spending a lot of time for them having chit-chats and unplanned long conversations and MORE ATTENTION and care about their works. In some occasions, I was proposing MS thesis topics to her and she was ignoring them and not even talking about them or giving any feedback. I was noticing MS students are assigned to her more favorite PhDs students even though my work was closer to those topics. I noticed she had opportunities of having involving me in collaborations with others people of her network, but she never mentioned that to me. During our colloquiums, she was treating/ignoring my questions/comments as stupid ones, and each time I had to send her a long email to precisely show her my point was worth considering. and more and more...
Well, I'm the international student of her group, and once she clearly states that she does not like international students as they are not good. But I was surprised by that expectation as her group does not have any considerable contribution in any top conference in the field (maybe only 1)! They are normal Ph.D. students doing normal research. I know I am not an MIT or Stanford student, but based on the external peer-feedbacks I received from other experts in my field, I do not see any reliable basis to be treated that way! At least i deserved having feedback if i was doing something wrong!
Anyway, in the end I managed to supervise my Ph.D. work totally by myself and do my PhD project the best i could, and i think my achievements are good enough for the PhD level.
But my concern is what she might do in my defense day. A professor with that kind of biased mind against a student can act like a monster in a defense session.
Also, I aim to continue in academia at least as a post-doc for now. But, I'm afraid how she might react when being asked as the reference regarding my Ph.D. work. So i'm afraid she can ruin my career future if she wants!
