I am interested in a PhD in biostatistics / epidemiology and currently thinking of writing a good research proposal. Can anyone please suggest the format, length, and some useful links regarding this.
probably. you could come up with your own ideas but you may not be in a position where you are going to be able to determine whether the data you need is going to be available or even exists!
I am interested in epidemiology from a very statistical and mathematical point of view. Most projects (in my opinion) on findaphd are more biological in nature.
