CL001,
I hadn't looked at NIH before. I work in collaboration with a hospital and when I mentioned to my collaborator there last summer that I want to apply to grants, he discouraged NIH at this point in my studies because he said you'd need half of your goals proved with preliminary data to even get considered for funding. So this is the first time I'm hearing about NIH F31. Yes I'm switching labs, and trying to coordinate both finishing what I can in my current lab and trying to find external funding with help from people from my committee. You know, people generally think committees are useless in grad school, but I'm really glad they exist. I'd be literally crying under a rock without mine.
I'm waiting for nsf results to know if I'm eligible or not for something internal that's due later this summer. If I get the nsf, I would be ineligible. If I don't, the hustle starts again. And since I need to change labs, the proposal I'd been intending to submit for the summer deadline needs to be scrapped or at least changed significantly, since no one else in the department works with what I currently do.
