Recently I joined a PhD program in a small unknown university in Asia. In the department, most of the faculties work on material and nano science except a professor who works on Astrophysics. The astrophysics professor agreed to be my supervisor and he asked me to work in the field of X-ray astronomy. However, he is not active in research these days and his other PhD students are given free hand to work on their own chosen field in astrophysics without much support from him. He is just being the supervisor for namesake and only helpful for official purpose like signing official papers, writing recommendation letters for the students to attend workshop and astronomy schools at other institutes. He is not actually helping the students in terms of research. As the professor holds an associateship with a research institute, he told me that he can send me to the institute so that I can hook up with a professor known to him, who can help me in my research in X-ray field. So, I have to run behind that professor in that institute if I have to work in that field of astrophysics and that institute is very far from my current location. Moreover, as I am new to astrophysics, I have not so much interest in astrophysics and I have no motivation to work on X-ray astrophysics. My main area of interest is in the field of theoretical aspects of Cosmology and General Relativity. However, I have not much prior exposure to the field; I only attended a school on Cosmology and General Relativity while I did my MSc in 2008. In this situation, I spoke to my supervisor and asked him if I can work on Cosmology or General Relativity instead of X-ray astrophysics. He told me that I can work if I want, but I have to work all alone as he cannot help me as he has no knowledge of either GTR or Cosmology. He further told that nobody is going to actually help in PhD research. I have to work alone without help from anybody and publish at least a research paper in an International Journal to fulfill the requirement for PhD thesis in my university. So, my question is, will it be possible for me to work on theoretical Cosmology or General Relativity all by myself without seeking any assistance from anybody by teaching the necessary foundations of physics and programming tools all myself? In the meanwhile, I can attend schools, workshops and conference on Cosmology and related field to enhance my knowledge of the field. It is my belief that I need a strong motivation to drive me to these long 4/5 years of PhD research. In this situation, will I be able to publish paper in international journal of repute and successfully able to finish my Phd and get a post doctoral position? What do you think I should do in this position of mine? Even if I have to work on X-ray astrophysics, I have to work alone and teach the subject and software skills myself. I am also not in position in this stage to look out for new program in another university as I am already 35 years old. Some Professors told me that I cannot research all alone in Cosmology and GTR as these days the field is in very advance stage and if I do it is risky business. What shall I do? I hope in most universities, almost all the theoreticians work and teach all alone to get their research papers published and get their PhD. In advance, I want to thank you all for your valuable and timely response in this situation of mine. Thanking you!
