Aim for verbs that are more specific to the actual contribution you made. For every sentence, challenge yourself to remove as many words as possible without changing the meaning of the sentence. Keywords cited by grant-funding agencies, easily recognizable by any faculty member, should be included in relevant sections of your Faculty Cover Letter.
Therefore, the primary purpose of a Faculty cover letter is to capture attention and generate interest among members of the specific department for which you are applying.
If you make it over this first hurdle, the cover letter should then serve as a letter of introduction.
The faculty cover letter connects all other application material, such as the Research and Teaching Statements, CV, and References.
Would these former and future relationships lead to additional funding for your lab?
If so, suggest more unusual avenues of additional funding.
