Should I write "we" or "I" in my research statement? I am currently in the process of applying for tenure-track assistant professor jobs.
I was wondering whether I should write "we" or "I" in my research statement.
While it is true that I did not do all the research on my own,
I have heard that in a research statement,
I am trying to sell my research agenda
and thus should use "I" rather than "we".
Nevertheless, I get an odd feeling as if I am taking all the credit for something that was done with other researchers.
A research statement is a mix of past and future.  

When you are talking about the past, you should be honest about the fact that you are not working in isolation---in fact, that is a good thing.  Use "we" or "my collaborators and I" or whatever most accurately describes what actually happened.

The other key part of a research statement, however, is your views about the future: what you think is important, what your ambitions are for the future, etc.  Those are unambiguously your own opinions, and should be "I" statements.
