I am a first year PhD student. I have no issues regarding academics and relationships with faculty. Unfortunately, there is a fellow student in the department who is making my life very difficult. The student regularly hounds me and the other students for various forms of help and gets aggressive when such help is not provided. The student also harasses us with constant phone calls and sometimes even stalks us. Despite persistent complaints to the department, they seem to be dragging their feet with the issue. Essentially the department considers this a non-academic issue and therefore expects us to sort it out ourselves. So this student will probably be around in the department for the foreseeable future.
As a result, I am considering transferring to a different PhD program at another university. This is still my first year and I haven't committed to an advisor yet. I am wondering how frank I should be in my transfer applications. After all, if I understand correctly, transferring PhD programs is generally looked down upon right? Would this situation have enough weight in the eyes of the application reviewers to justify a transfer?
