I am currently working on a research project at a non-academic institution as part of a summer internship. They've brought me in to work on a topic that is somewhat within my area of study. However, there is nobody here who shares my field. There are other folks with related expertise, but it's not quite similar enough to be of help (at least not at this stage in the research). Furthermore, my work involves data that is quite different than what I'm used to working with. It's enough to say that the data requires different analysis techniques than what I'm used to--to the extent that the application of this research is whole sub-field in its own right.
I'm obviously reading papers to familiarize myself with this sub-field, and I've also reached out for direction from colleagues who have plenty of experience in this area. The real problem stems from the lack of an experienced adviser/supervisor who can help direct the project. As much as I'd love to be capable of doing this solo (and this will probably be a good trial-by-fire learning experience), I'm concerned that I'm still too novice of a researcher to go it alone.
I'm not throwing this project away, so what are some steps I can take to make progress despite this limited supervision?
