I need some constructive advice about my dissertation topic. I am literally just
Thing is, the few professors in my department who work in this area don't want to be bothered, so I'm stuck.
I find it hard to believe that professors in your department who work in your area of research "don't want to be bothered" with questions about a research topic from someone within a year of starting his/her dissertation. If any of those professors are your advisors, it's their job to field such questions. If, after gently persisting, you can't get constructive advice about your dissertation topic from faculty in your own department, you should seriously consider transferring to a program where you can get such advice.
