Volunteered or Voluntold? The Motivations and Perceived Outcomes of Graduate and Postdoctoral Mentors of Undergraduate Researchers

<br> <b>Graduate students and postdoctoral researchers (postgraduates) in the life sciences frequently mentor undergraduate researchers, especially at research universities. Yet there has been only modest investigation of this relationship from the postgraduate perspective. We conducted an exploratory study of the experiences of 32 postgraduate mentors from diverse institutions, life sciences disciplines, and types of research to examine their motivations for mentoring and their perceived outcomes. Although some postgraduates reported feeling pressured to mentor undergraduate researchers, all expressed personal motivations, including both agentic (self-focused) and communal (community-focused) motivations.
