I am writing here to get good advice for my career. I completed my PhD in Mathematics last year. I was quite happy after my PhD that I have gained a PhD degree, but I don't have any idea what I could do with this degree. Normally people apply for postdocs after doing PhD to become more independent and gain more exposure to research in their field. However, what can they do if their supervisor does not support them to apply for postdoc positions? What if their supervisor says "you are not an independent researcher, so I don't think you could really sell yourself as an independent researcher?"
I am stuck in my career after having lots of negative feedback from my PhD supervisor, who always says not to apply anywhere, and just stay here (my country) and integrate yourself with your colleagues. How could someone stop you or discourage you to apply anywhere else in the world?
One of the biggest and toughest situations for me is the field I had chosen for doing PhD has no funding all around the world and I can hardly find postdocs in my field. And even if I find an advertisement of a post relevant to my field, my supervisor discourages me from applying by saying that that is not exactly relevant to the field (topic) in which you had done your PhD. It's so weird to me that is it necessary to have the same topic for a postdoc to apply in which a person had his PhD? Can't we slightly change our research topic relevant to the field (same background).
The main problem is to apply for any postdoc we need a strong reference letter from our PhD supervisor. What can people do if they doesn't know what their supervisor writes about them in the reference letter? I spent four years in my PhD and not once did I did realise that my PhD supervisor is unhappy with my work. But now when I am back in my country on completion of my PhD my PhD supervisor has negative thoughts about me that I can't sell myself as an independent researcher, I will need guidance and direction.
And he is probably true, because most of my work in my PhD was done by him. And he never let me be independent throughout my PhD. I don't even know how people find topic of research/problem to work on and how do they find techniques to attach on the problem. I had been given a problem with my supervisor and direction as well. I had done all the coding by myself advised by my supervisor and later analysing results and proving those results was done by him. In the end of my PhD when I was writing my research paper I put his name on it where he said no to me and writing paper solely with my name only.
Currently, I am a lecturer in my country. However, to survive in an academia I have to publish papers and supervise master's students. However, I am not feeling myself independent in research, due to the reason I am applying for some postdoc positions, where I have no support from my PhD supervisor. What should I do at this point? Should I leave academia? Should I go to industry? To join an industry what skills I do need to have? How can I make myself a perfect candidate?
I am really stuck in my career without having any support from my PhD supervisor after PhD. I am looking for some really good suggestions for my career. I shall really be grateful.
