As far as which research project you might decide to undertake, you need to work out what you would like to focus on potentially, after which you should undertake some preliminary reading (primary, literary-critical, and other theoretical sources), then write your research proposal with a bibliography citing the sources consulted. After doing so, you are ready to apply formally.
So to reiterate, you may well need to undertake preliminary research in a relevant literary area before further contact any of our staff, unless you want to confirm an area you have in mind is relevant to their interests. Remember, if you want to study for a PhD this is all good practice, and not wasted effort. However good your idea is for a research degree, it is the applicant who must do some research into their own ideas and they should not expect staff at Brunel to do so on their behalf. Some of our tutors may be prepared to work with you on this process, but this is a matter for their choice, and they simply may be too busy at certain times even to contemplate doing so.
