Hi! I'm applying to graduate schools in Statistics (some PhD, some Master's). The thing is, my undergraduate degree is in Civil Engineering--not too unusual, most of the schools I'm applying to mention that their grad students often come from other fields, including schools that only have a PhD program.
I actually have a decent amount of experience in research through undergraduate programs and I think my letters of recommendation and my resume/CV will show that I'm an independent worker and capable of going through a PhD program. But, I have next to no idea what, specifically, I'd want to study. Yes, I think Statistics is cool and yes, I'm totally ready to spend the next four or so years of my life studying it, but I simply don't know enough to say, for example, "I want to study network modeling as applied to healthcare systems."
I also don't know enough to name-drop or talk about my research interests in detail. Is this ok? I think I can find a general direction that I'd be interested in--but I'd rather it happened naturally, i.e. after taking grad-level courses.
Thanks in advance for any advice.
