Hi, I would like to ask you all if you can five me some guidence on how to procede in following situatio . First i will give some context for my situation. I have finnished my undergraduate and my masters degree in institution that is outside EU, during my masters degree i had done research in string theory. Research that i had done is in really niche area and scince there were no other string theory teams in my country that was only area that i had an oportunity to do research in. Now, im planing on applying to EU universities for PhD, mainly German and British universities, and i would like to do my PhD in different subfield of string theory. In order to give my application i have to write research proposal, and this is where following problem arises. For subfield that i did my MSc i kow what could be good research topic, but for subfield that i would like to do my PhD in i just have general idea of what i would like to do. So im stuck in following situation, i think i knkw what my possible courses of action could be, and i would like if you could make me decide. Situation number 1: i get all posible literature on my interest topic and figure out what could be good research proposal. This would take too much time and i could end up that with somethin that is over my head or something that is of no particular interest for anyone exept me. Situation number 2: I contact potential PhD supervisor that work in field i would like to do PhD in and explain to him mine problem and ask him if he could give me some guidence on recomend me some research topic. Situation number 3: I just continue research i did for my MSc but at different university. This is a situation that i would not like to do, but if i must i will. I would like for you to say to me what would be my best course of action, i personali think it is situation number 2, but i dont want to make a fool of my self and ruin any potential chance to work with my future potential supervisor. Also, i know that for field of general relativity there is a site called Hyperspace where all posible predefined research topics are posted, if there is a similar site for string theory i would really like to know about it. Im sorry for any granatical mistakes, this is my first post ever and im posting from a phone. If you need me to expand on anything that i had wrote just ask and i will do it.
