I'm guilty of that too...I guess the important part isn't rambling itself, but knowing/admitting that you ramble, right? I am really glad the preventative side of healthcare is coming to the fore, be it environment, gene-mapping & mutagenic behavior, or nutrition. You've probably seen this clip before on regenerative medicine, but if things like this are coming in the next decade, then I can't wait to see what we all find through our research:
One of the ideas I had for a focus is based on accreditation. The current process with the Public Health Accreditation Board (PHAB) is a national beta test - starting this summer - for a group of PH agencies that will measure how well they function within 10 identified public health standards (taken from the CDC's National Public Health Performance Standards Program [NPHPSP] and the National Association of County & City Health Officials [NACCHO]). Assuming everything stays on track, in 2011 the accreditation process will be opened up for anyone. For those that volunteer for it, I think it would be interesting to measure and compare how (un)successfully the transition is for a sample of small, medium, and large health agencies, and see if any best (or worst) practices are out there for managing the change.
One other one is another survey of best practice, this time for the rehabilitation of homeless that fall under the "dual-diagnoses" category... those with drug addiction and mental illness. I'd have to see what current research is out on that already, though.
Ok, now I'm the guilty rambler... but I did want to ask something. How did you present yourself in your personal statement & interview if you didn't have a specific research question yet? In other words, what level of focus-specificity do you think tells the faculty you are interested and a good fit? Was the interview them grilling you on your focus and seeing if you had thought it through?
