Bring the degree and transcripts, a detailed project or duty description, and any documentation of the applicant's prior biological research experience. A supervisor's written account of the role's structure adds useful weight.
Get the project description in writing early
Many research postings are drafted loosely, so ask the hiring lab to put the actual duty breakdown and supervision structure in writing rather than relying on a general posting. If the degree is in an adjacent field, add course-level detail showing where the biological coursework or research fits. Prior publications or research reports, where they exist, help demonstrate genuine biological work history.
Insist on a written project description even where none exists, because research postings are drafted loosely and a general posting will not answer the questions asked of it. The set to assemble is the degree parchment, the transcript, a duty and supervision description signed by the lab, and evidence of prior biological research work such as reports or publications. Where the degree sits in an adjacent field, add course-level detail showing where the biological content lies, and consider an evaluation whose terms of reference name that question.
