In a somewhat similar vein, I'll be in the discipline I specified (physics) but in recent months my research has changed directions so I don't think I'll be researching what I wrote on in my app. To be honest, I don't think I will end up going anywhere near what I wrote on in my app in my future work. Does anyone know if NDSEG will care? I asked someone who got it last year and someone who got it two years ago and they both said aside from the abstract that we have to submit about a month before funding starts, they've never had to check in with anyone for continued funding. However, there's another post buried deeper in this thread where a past winner said that they're paired with a mentor who they expect to have lots of communication with, so it would be very awkward for them to change topics.
