Very helpful, Thank you. (up)

Hi all, my background is in Public Health and I'm considering to do a Phd in this field. I would like to do this next year in the UK. I have a strong interest in HIV/AIDS and the impact of this in Jamaica however being a novice to primary research I am not sure how to go about this. In particular defining the research title and the content of the research proposal hence any tips, advice or a point in the right direction of a website, book or journal to read will be greatly appreciated.
