My question is rather straight forward. I am currently applying for postdoctoral positions in (pure) mathematics. I am almost done writing my research statement and it seems to come out to about seven pages. Is that too long?
A similar question has been asked herehere, but it seems to deal with applications for graduate school.
In my research statement I have described my previous work (which has resulted in four published/submitted papers and two currently in progress), as well as some short term and long term projects that I plan to work on. Part of the reason that the statement is turning out to be so long, is that I work in two (a priori disjoint) fields of (pure) mathematics, often applying one to the other. So it takes about two pages to describe the motivation and the necessary background.
So, again, is seven pages too long? Do you have any specific advice about preparing a statement for research on an intersection of different fields?
