Editorial commentary

A research mentor is an experienced researcher who provides career, intellectual, or professional guidance to a less experienced researcher (the mentee). The relationship is normally chosen rather than assigned, can cross institutional lines, and — unlike formal supervision — carries no evaluative authority over the mentee’s funding, progression, or degree outcome. Many institutions and funders now formalise what was once an informal relationship through structured mentoring programmes, learned-society schemes, and funder-mandated mentoring plans attached to training grants and career-development awards.

How it differs from related terms: A doctoral supervisor holds formal institutional accountability and evaluative authority a mentor does not. A career sponsor is a distinct, related role involving active advocacy — using one’s own standing to open doors for someone — rather than the guidance-focused relationship a mentor provides; the two are frequently confused but describe different kinds of support. The expectations of a specific mentoring relationship, including its scope, cadence, and duration, are typically set out in a mentoring agreement.

A senior researcher providing monthly career guidance to a postdoc at a different institution through a learned-society scheme is acting as a mentor; the same senior researcher formally assessing a doctoral student’s progress toward their degree is acting as a supervisor, even if the day-to-day interaction looks similar.
