I am submitting a postdoctoral application that requires an external arm's length referee to write an evaluation of the proposal to be submitted with the application. The referee should be an acknowledged specialist in the proposed area of research. I am thinking of asking a scholar who I have only met once at a conference and have no other connections with. This scholar has contributed substantial theoretical and empirical insights to my topic, and accordingly I draw on their work heavily in my proposal. In particular, I adopt a theoretical framework that they have helped develop in my field and suggest that I am advancing a study conducted by this person.
If this person agrees to serve in this role, could this reliance raise concerns to the multi-disciplinary selection committee? In particular, I worry that the committee may think that I have biased the referee in my favour by relying strongly on their contributions, and specifically advancing their theoretical and empirical work.
Thanks for your time!
